PostgreSQL version: 14.4
Operating system:   AWS RDS
Description:       

Hello,

We recently upgraded our AWS RDS instances to PG 14.4 and are seeing weird
performance degradation.

First things first, did you do an ANALYZE on the database after the upgrade?  (Maybe RDS does it for you, I don't know.  But it isn't worth looking into anything else until you make sure that that has been done)

Cheers,

Jeff
