It did succeed, it just happened to return 0 rows. Use pg_numrows to see
how many rows were returned.

PHP Bug Type: PostgreSQL related
Bug description: pg_exec returns true even though it failed
When I execute the following code segment with the $EmailAddress and
$Password variables set to values that exist in the PostgreSQL 6.5.3 table,
everything works fine.
When I execute it with values that are NOT in the table, pg_exec still
returns a "true" value even though the SELECT statement never found any
matching rows. (This is contrary to what the documentation implies when it
tests for !$result.)
The actual value of the $query variable, even when the query sent by the
pg_exec function fails, is "Resource id #2". Because it's not falst,
there's no way to test whether the query succeeded. So when the program
goes on to execute the pg_fetch_array function, the $query variable points
to nothing and the program dies with an error message.
-------------------------------
<?php
// -- This module checks a username and password to see who the user is.)
$db = pg_connect("", "", "", "", "tracker");
if ($db) {
$SQLQuery = "SELECT userid FROM users WHERE username = '" .
$EmailAddress . "' AND password = '" . $Password . "';";
$query = pg_exec($db, $SQLQuery);
if ($query) {
$row = 0;
if ($data = pg_fetch_array($query, $row)) {
// Etc...
