postgres and acid

["neal" <ntimm () stingrey com>]

Hello I'm not to familiar with postgres and and getting this error when
trying to connect to acid.  Running redhat 7.2 postgres 7 and snort
1.8.3 snort has no problem connecting as I can see data in the data base
just having the problem viewing through acid any help would be
appreciated.
 
Thanks.
