(What did you try? What did you get?)

It's not clear why you have a question mark in the SELECT clause, but
you can solve the WHERE clause part by making the placeholder cover
the entire condition, rather than try to pass in only part of it
via the arguments. So try this instead:

$SQL = 'SELECT relname FROM pg_class WHERE relname LIKE ?';
$sth = $dbh->prepare($SQL);
$count = $sth->execute('%a%');
print "Count is $count\n";
