Re: error while starting database - Mailing list pgsql-bugs

Since you do not have a /tmp folder in your filesystem, it may be
that the server cannot create the socket file and so it will not
start.  You cannot telnet to port 5432, because no service is
listening on that port.  The PostgreSQL server is not started.

I'm sorry I didn't answer you last night.  It was 02:00 in the
morning when I got home and sent you the previous message, I went
straight to bed after checking my mail.  In any case, the server
specifically calls out an error creating "/tmp/.s.PGSQL.5432".  I
would start by creating a world-writable /tmp folder.  If that allows
you to start the service, then you can do a backup with pg_dumpall.
