First, I would highly recommend you investigate the perl DBI abd DBD::Pg
modules -- they handle variable placeholders quite efficiently and
correctly.
But for your problem above, surely you must use single quotes around any
string you include as a literal in an SQL query.
$res = $conn->exec("select cust, contact, user_name, email from $t
where user_name = '$c'");
