DB query error

Hi,

can somebody help me with this problem?

When I install counter module to my drupal these warnings occured:

warning: pg_query() [function.pg-query]: Query failed: ERROR: syntax error at or near "IGNORE" LINE 1: INSERT IGNORE INTO counter (counter_ip, counter_date, cou... ^ in ...\includes\database.pgsql.inc on line 138.

user warning: query: INSERT IGNORE INTO counter (counter_ip, counter_date, counter_page) VALUES ('127.0.0.1', '2009-04-26 15:40', 'node') in ...\modules\counter\counter.module on line 121.

I am newbie in drupal and I do not know how PHP or SQL works...

How can I fix this?

Thank you...
