INSERT IGNORE is not permitted in PGSQL

I've found an issue located on counter.module line 174:
INSERT IGNORE is not permitted in postgresql.

You can see here how to fix this bug:

Provisionally on my code I've added the pqsql case but I expect that this is not the correct way to fix it:
case 'pgsql':
$sql = " INSERT INTO {counter} (counter_ip,counter_date,counter_page) ".
" VALUES ('%s','%s','%s') ";
break;

Hope you can fix it soon.
