Re placeholders: PostgreSQL's DBD::Pg has an attribute 'pg_placeholder_dollaronly' which when set to 1 makes placeholdering (ordering or repeating) a little easier (fsvo easy):


$dbh->{pg_placeholder_dollaronly} = 1; # default is 0
my $sth = $dbh->prepare('SELECT * FROM people WHERE lastname = $1 AND 
+firstname = $2');
