Crashes PSQL when table has high Partition Count

[GEverding]

I've caused psql14 to crash multiple times trying to run pgmetrics with a hash partitioned table with 1024 partitions.

Seems to be a common problem. I'm pretty sure pgwatch2 did something very similar

It's not a pgmetrics and it's not a pgwatch2. You have misconfigured instance. Check your settings and tune memory, especially huge_pages
