a) user = postgres b)pg_dump version = /usr/bin/pg_dump -V pg_dump (PostgreSQL) 13.16 c) DB version select version () ; version---------------------------------------------------------------------------------------------------------- PostgreSQL 13.16 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44), 64-bit use this script for backup pg_dump -Fp -p 5432 -U "$USERNAME" "$DATABASE"
using username = postgres for one of the DB (ver 13.16), it worked fine by doing oldvm = pg_dump from ver 13.16 andlater restoring in new VM with new OS and new db binary 15.09, post creating dummy db (appln related) and restoring the pg_dump from oldvm .

It is either psql or pg_dump. psql is the CLI client for the Postgres server. If you are using psql as an alias for Postgres(sql), don't, it only adds confusion. > > Will be pg_dump and pg_restore to restore in the new VM with new OS [OS= > amazon linux 2023] and new DB bin pgsql ver 15.09. > > We were told by AWS team, in the new VM tagged OS [OS= amazon linux > 2023] , pgsql Ver 13.16 is not supported Not sure why?
