The default Unix domain socket file should be in /var/run/postgresql/
The official default directory for Unix domain sockets is /tmp. This is changed by some distributions to /var/run/postgresql, but that is not very convenient for PGAdapter, as it would require elevated permissions to be able to write anything there.

The default Unix domain socket file is in the directory
/tmp/, but some PostgreSQL distributions use/var/run/postgresql/as the default directory. If anyone tries to change the directory that should be used by PGAdapter to/var/run/postgresql/, the probability is very high that it will cause a permission denied error when PGAdapter tries to write to that directory. This PR adds error handling for the case that a user specifies an invalid or inaccessible file for Unix domain sockets.Also adds additional tests for Unix domain sockets, and changes some of the psql tests to use domain sockets to connect instead of TCP, to verify that our domain sockets implementation also works with psql.
