Review Change Stack

Summary by CodeRabbit

  • New Features

    • Added support for optional SSL configuration when connecting to PostgreSQL.
    • SSL settings and certificate files can now be derived from the database connection URI.
  • Bug Fixes

    • Improved connection initialization with a validation query.
    • Initialization failures are now logged before being reported.
    • Removed unsupported connection parameters to improve compatibility.

Walkthrough

PostgreSQLLogProvider now supports optional SSL configuration from constructor options or URI parameters. It loads certificate files, removes libpq-specific parameters, tests the connection during initialization, and logs failures before rethrowing them.

Changes

PostgreSQL SSL initialization

Layer / File(s) Summary
Provider connection initialization
src/server/logs/postgres/provider.ts
The provider accepts SSL options, derives settings from options or the connection URI, loads certificate files, removes SSL-specific URI parameters, initializes PostgreSQL, and runs SELECT 1. Initialization failures are logged and rethrown. Bucket SQL expressions remain unchanged while descriptive comments are removed.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to c93d6

The change enables TLS connections but currently exposes database credentials in logs, can build incorrect connection URIs, and may silently weaken or misconfigure mutual TLS when certificates or sslmode settings are invalid. These issues can cause authentication failures, connections to the wrong database, or credential disclosure, so the PR is not ready to merge until corrected.

Drop the fire-and-forget connection test.

The async IIFE is not awaited and its result is not stored. A failure only prints a message, so the provider still reports success and the real error surfaces later on the first query. Remove the block, or expose an awaited init() method that the caller in src/server/logs/index.ts uses to fail startup.

Remove the debug logging; line 74 prints the connection URI with the password.

cleanedUri contains the userinfo section, so the database password is written to stdout on every provider construction. Application logs are commonly shipped to aggregators, so this exposes a credential. Remove line 74 and the remaining [DB Debug] statements, or reduce them to messages that contain no URI, host, or certificate details.

postgres.js 3.4 ssl option values sslmode require verify-full rejectUnauthorized

💡 Result:

In postgres.js, the ssl option is used to configure TLS/SSL connections [1][2]. Unlike some other PostgreSQL drivers that parse sslmode parameters from connection strings, postgres.js is designed to have its SSL configuration explicitly defined via an ssl object in the configuration settings [1][3][2]. The ssl option accepts either a boolean (e.g., ssl: true or ssl: false) or an object that conforms to the Node.js tls.connect options [1][2][4]. Key points regarding the options you mentioned: - sslmode: postgres.js does not natively interpret or support sslmode as a top-level connection string parameter. Configuration that would typically be handled by sslmode (such as require, verify-ca, or verify-full) must be managed by setting the appropriate properties within the ssl object [1][2]. - rejectUnauthorized: This is a standard property within the Node.js TLS configuration object [1][2][4]. Setting ssl: { rejectUnauthorized: false } allows connections to servers with self-signed or otherwise unverified certificates [1][3][2]. While this is sometimes used to bypass SSL errors with cloud providers that do not support verifiable certificates, it makes the connection vulnerable to man-in-the-middle (MITM) attacks and should be used with caution [1][2]. - verify-full: To achieve the equivalent of verify-full (which verifies both the CA and the server identity), you should provide the necessary CA certificate in the ssl object using the ca property. When a ca is provided and rejectUnauthorized is not explicitly set to false, the Node.js TLS implementation will perform certificate verification [1][2][4]. Example configuration for a secure connection: const sql = postgres('postgres://host:port/database', { ssl: { ca: fs.readFileSync('./path/to/server-ca.crt'), rejectUnauthorized: true // Enabled by default, ensures server identity is verified } }) If you are using a connection string that includes sslmode, be aware that postgres.js will generally ignore that parameter [1][2]. You must ensure your security requirements are defined explicitly within the ssl object [1][2].

site:github.com/porsager/postgres tag v3.4.9 ssl rejectUnauthorized postgres.js null ca cert key

💡 Result:

In the postgres.js library, the ssl option allows passing an object containing standard Node.js tls.connect parameters [1][2][3]. When you need to provide SSL/TLS configuration, such as custom CA certificates, client certificates (cert), or private keys (key), you pass them as properties within the ssl object [4]. To handle self-signed certificates or other certificate verification issues commonly encountered with cloud providers (like Heroku or Google Cloud SQL), it is common practice to set rejectUnauthorized: false [1][2][3][4]. Example configuration: const sql = postgres('postgres://username:password@host:port/database', { ssl: { rejectUnauthorized: false, // Use with caution; vulnerable to MITM attacks [1][2] ca: [fs.readFileSync('path/to/server-cert.pem')], // Optional: CA certificate [5][3] cert: fs.readFileSync('path/to/client-cert.pem'), // Optional: Client certificate [4] key: fs.readFileSync('path/to/client-key.pem') // Optional: Private key [4] } }); Important considerations: 1. Security Risk: Setting rejectUnauthorized to false disables certificate verification, making the connection vulnerable to man-in-the-middle (MITM) attacks [1][2][4]. It is recommended to use properly verified certificates whenever possible [4]. 2. Deno Usage: If you are using postgres.js in a Deno environment, the ssl options are polyfilled to Deno's tls implementation [6]. Some users have encountered differences in how certificates are handled compared to Node.js, and in some cases, Deno-specific flags like --unsafely-ignore-certificate-errors have been discussed, though these are also insecure [6]. 3. Documentation: The official postgres.js README explicitly documents the pattern of using rejectUnauthorized: false for production environments where verifiable certificates are not supported by the hosting provider [1][2].

🌐 Web query:

postgres npm 3.4.9 source ssl option tls.connect rejectUnauthorized

💡 Result:

In the postgres.js library (npm package postgres), the ssl option is used to configure TLS/SSL connections [1][2]. When provided as an object, these options are passed directly to the Node.js tls.connect method [1][3]. Setting rejectUnauthorized: false within the ssl object instructs the TLS layer to disable certificate validation [1][2]. This configuration is commonly used in environments where self-signed certificates or specific cloud provider configurations make verifiable certificates unavailable, though it creates a vulnerability to Man-in-the-Middle (MITM) attacks [1][2]. Example configuration: const sql = postgres({ ssl: { rejectUnauthorized: false } }); It is important to note that node-postgres (the pg package) and postgres.js are distinct libraries. While both allow passing SSL options, their connection configuration, especially regarding connection strings and sslmode parameters, can differ significantly [4][5][6]. Always consult the documentation specific to the library you are using [1][7].

raw.githubusercontent.com porsager postgres v3.4.9 src connection ssl tls.connect ca cert key

💡 Result:

In the postgres.js library (used in version 3.4.9), the ssl option is designed to accept either a boolean or a configuration object [1]. When provided as an object, it is passed directly to the Node.js tls.connect function [2], allowing you to specify SSL/TLS connection parameters, including CA certificates, client certificates, and private keys [3][2]. To configure SSL/TLS with CA, certificate, and key files, you can provide these as options within the ssl object [3][2]: const sql = postgres('postgres://username:password@host:port/database', { ssl: { ca: fs.readFileSync('path/to/ca.pem'), cert: fs.readFileSync('path/to/client-cert.pem'), key: fs.readFileSync('path/to/client-key.pem'), // Optional: rejectUnauthorized: true is default for secure connections } }); Key details regarding this configuration: - Node.js compatibility: Because the ssl object is passed to Node.js's tls.connect, all standard options supported by the Node.js tls module (such as ca, cert, key, passphrase, and rejectUnauthorized) are supported [2]. - Security note: If you are connecting to a service that uses self-signed certificates and you cannot provide a trusted CA, you might see a DEPTH_ZERO_SELF_SIGNED_CERT error [2]. While some users work around this by setting { ssl: { rejectUnauthorized: false } }, this makes the connection vulnerable to man-in-the-middle (MITM) attacks and should be used with caution [4][5][6]. - Type definition: The library's internal TypeScript definitions explicitly state that the ssl option can accept an object for these advanced configurations [1].

Map sslmode explicitly

postgres 3.4.9 passes the ssl object to Node.js TLS and does not implement libpq sslmode semantics. Because {} uses Node’s default rejectUnauthorized: true, sslmode=require can reject self-signed certificates. Map require to { rejectUnauthorized: false } and map verification modes to explicit certificate validation settings.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Throw when a configured certificate file is missing.

loadCert logs an error and returns null. Initialization then continues with ca, cert, or key unset. Two bad outcomes follow: mutual TLS silently degrades to a connection without a client certificate, and the operator sees only a later opaque TLS handshake error. Configuration was explicit, so fail fast.

🛡️ Proposed fix
       const loadCert = (label: string, path?: string | null) => {
         if (!path) return null;
         if (!fs.existsSync(path)) {

🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win

Fix the URI reconstruction; the query string is placed before the database path.

Line 72 concatenates the query string before url.pathname. For postgres://u:p@h:5432/blocky?sslmode=require&application_name=x the result is postgres://u:p@h:5432?application_name=x/blocky. The database name becomes part of the query segment, so the driver connects to the wrong database or fails at startup. The template has three more defects: url.username is not percent-encoded, an empty password produces user:@host``, and an empty url.port produces `host:`.

Mutate the parsed URL and serialize it instead of rebuilding the string. URL.toString() preserves userinfo encoding, port omission, path, and parameter order.

🐛 Proposed fix
-    const cleanParams = new URLSearchParams(params);
-    cleanParams.delete("sslmode");
-    cleanParams.delete("sslcert");
-    cleanParams.delete("sslkey");

In `@src/server/logs/postgres/provider.ts` around lines 63 - 72, Replace the
manual cleanedUri template around cleanParams with mutation of the parsed URL:
remove the forbidden parameters from its searchParams, then serialize the URL
via its existing URL serialization method. Preserve the cleaned URI’s path,
encoding, optional password, optional port, and remaining query-parameter order.
