Dear, I'm new at postgresql and I've installed it on a Debian 10
(stable) server.
I don't know why, but after executing the psql command, I see this message:
psql (13.1 (Debian 13.1-1.pgdg100+1), server 12.5 (Debian 12.5-1.pgdg100+1))
It seems both the posqgresql 12 and 13 are installed at the same time...
I think I've installed postgresql 12, but here I see I have these
packages after upgrade with apt:
ii postgresql 13+223.pgdg100+1 all
object-relational SQL database (supported version)
ii postgresql-12 12.5-1.pgdg100+1 amd64
object-relational SQL database, version 12 server
ii postgresql-13 13.1-1.pgdg100+1 amd64
object-relational SQL database, version 13 server
ii postgresql-client-12 12.5-1.pgdg100+1 amd64
front-end programs for PostgreSQL 12
ii postgresql-client-13 13.1-1.pgdg100+1 amd64
front-end programs for PostgreSQL 13
ii postgresql-client-common 223.pgdg100+1 all
manager for multiple PostgreSQL client versions
ii postgresql-common 223.pgdg100+1 all
PostgreSQL database-cluster manager
Is this correct or do I have to uninstall the postgresql 13 packages ?
Within psql CLI, the version is:
SELECT version();
PostgreSQL 12.5 (Debian 12.5-1.pgdg100+1) on x86_64-pc-linux-gnu,
compiled by gcc (Debian 8.3.0-6) 8.3.0, 64-bit
(1 row)
Thanks a lot!!!

"Correct" is in the eye of the beholder. Leave both installed, or deinstall
the one you don't want.

Run the pg_lsclusters to see what database instances (Postgres confusingly
calls them "clusters") are configured.
Also, echo $PATH to see what binaries that Debian will see first.

Dear Ron, thank you so much for your help.
Please see the outputs:
$ pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
12 main 5432 online postgres /var/lib/postgresql/12/main
/var/log/postgresql/postgresql-12-main.log
13 main 5433 online postgres /var/lib/postgresql/13/main
/var/log/postgresql/postgresql-13-main.log
# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
But if I wanna uninstall postgresql-13 and postgresql-client-13, maybe
the system will uninstall all the postgreslq packages (including
version 12)???
# apt remove --purge postgresql-13 postgresql-client-13
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages will be REMOVED:
postgresql* postgresql-13* postgresql-client-13*
Thanks in advance again, regards!!!

It means that you use the PostgreSQL client 13 version, which is connected on
the PostgreSQL server version 12. Because PostgreSQL 12 was installed
before and took the default PostgreSQL port, 5432. If PostgreSQL 13 has
been installed after, it listens on port 5433.
In order to confirmn, you can try to launch: psql -p 5433

It's useful to make migrations.

Why do you want to remove 13 and not version 12 ?

His application might not be tested and certified on v13. (Being a contract
DBA, I face this issue on a regular basis: company buys 3rd party software
from a small company which only tests on a small set of versions. Or the
company might not want to run their mission critical software on .1
software. Or the company is too cheap to upgrade working software even
though it's EOL.)
