[bug#46249] [PATCH] Update documented default PostgreSQL socket-directory

That's a dumb mistake on my part, thanks for fixing it.

Yes when the socket directory is enabled in PostgreSQL those tools try
to use it but with the default directory set to "/tmp". I have pushed a
patch on core-updates to set the default socket directory to
"/var/run/postgresql" like most of the other distributions.

In the meantime you can set the "socket-directory" field of
"postgresql-config-file" to #f to restore the previous behaviour.

Thanks,

Mathieu
