[arch-general] Postgresql with Systemd

[Paul Gideon Dann]

I'm having some trouble getting postgresql working with systemd.  The unit 
originally would fail to start, until I realised that the script it uses to 
start assume that the variables in /etc/conf.d/postgresql will be defined, and 
in my setup they were commented out.

Once I'd uncommented them, the unit starts OK, and I can connect using pgsql.  
However, there is no domain socket created at /tmp/.s.PGSQL.5432, which is 
clearly not right.  It means that phpPgAdmin is broken in its default 
configuration.

I'd be surprised if noone else had encountered this, although I can't find any 
obvious chatter online.  Has someone determined the best way to fix?
