1. I'm assuming that psql works fine? psql -h 127.0.0.1 mpact?
1b. Have you checked the port?? You ARE running postmaster with the '-i' option,
aren't you?
The recommended solutions are typically to use the DBI and DBD modules. Try man
DBD::Pg.
Alternatively: have you tried the setdbLogin method instead:
$conn = Pg::setdbLogin($pghost, $pgport, $pgoptions, $pgtty, $dbname,
$login, $pwd)
Opens a new connection to the backend. The connection
identifier $conn ( a pointer to the PGconn structure )
must be used in subsequent commands for unique identifica-
tion. Before using $conn you should call $conn->status to
ensure, that the connection was properly made. Closing a
connection is done by deleting the connection handle, eg
'undef $conn;'.
Hope this helps a little......
