If you do have a system user foo, you could sudo to it instead of postgres: # sudo -u foo psql -f central.sql -q FOO >I have looked here and my 'trust' lines look like this > >host all all 127.0.0.1 255.255.255.255 trust >host all all 192.168.11.238 255.255.255.255 trust You're missing lines for local, as psql uses by default unix sockets (as John Summerfield pointed out): local all all trust Note that this isn't very secure, as any user in the host can presume to be any other user, so you should change trust to md5 and make sure you have passwords defined for all postgres users. -- lfr 0/0 -------------- next part -------------- A non-text attachment was scrubbed...
