Hi Dominique,
you can use \conninfo in psql to show the database, user, host (or socket in my example), and port:
ewie@desktop ~ $ psql test
Null display is "".
psql (14.3)
Type "help" for help.
test=# \conninfo
You are connected to database "test" as user "ewie" via socket in "/run/postgresql" at port "5432".
