Yeah, that. You're apparently using a version of psql/libpq that
thinks the default Unix socket location is /var/run/postgresql;
but the postmaster you are using did not create a socket there.
(Probably it put one in /tmp instead, which is the out-of-the-box
default location. But some distros consider that insecure so they
override it, typically to /var/run/postgresql/.)
The easiest workaround if you have a mishmash of Postgres libraries
is to tell the postmaster to create sockets in both places.
See "unix_socket_directories" parameter.
