I've been stumped as to how to call psql from the command line without it prompting me for a password. Is there a enviornoment variable I can specify for the password or something I can place in .pgsql? I could write a perl wrapper around it, but I've been wondering how I can call psql -c without it prompting me. Is it possible? -Kenji On Mon, Apr 03, 2006 at 02:39:10PM -0400, Tom Lane wrote: > Kenji Morishige <kenjim@xxxxxxxxxxx> writes: > > Various users run a tool that updates this table to determine if the particular > > resource is available or not.
