- 9.5 is the version of the
psql
tool you are using. It get's updated at each installation of a new PostgreSQL. - 9.3 is the version of the DBMS you are currently connected to.
When running just psql
it connects to the default port 5432 so I'm guessing the 9.3 version of PostgreSQL is on that port. Try with psql --port=X
and set X
to a port of different PostgreSQL daemon; you should see different versions then.
