HiI'm working with AWS RDS PG instances that have been created over time, and that by now are a mix of several major/minor versions ranging from 12 to 15.The initial configuration and management is done from an EC2 instance running Debian 11, which has Postrgres 13.13.I already found out that there are compatibility issues if I use the client programs from the Debian VM when they're older than the server version.
Like what?
psql can sometimes be wonky when running against newer servers, as can PgAdmin4, but that's because they won't understand changed catalog tables.
Do the other client programs use new SQL features?
