Re: Where is my app installed?

Hi Arbol,

Try to find any binary e.g.

find /usr -name pg_ctl
/usr/local/pgsql/bin/pg_ctl
/usr/lib/postgresql/16/bin/pg_ctl

find /usr -name psql
/usr/bin/psql
/usr/local/pgsql/bin/psql
/usr/lib/postgresql/16/bin/psql

Later you may create a symlink or add in PATH.
Hope this helps.

Regards,
Ikram
