PostgreSQL combatibility

In order to be able to use the Apache Solr module with Postgres, please change in apachesolr_search.module on line 274:

From:
AND (r.rid IN (". db_placeholders($rids) .") OR r.rid IS NULL) LIMIT 0,1", 'b', 'bid'), array_merge(array($module, $delta, $theme_key), $rids));

To:
AND (r.rid IN (". db_placeholders($rids) .") OR r.rid IS NULL) LIMIT 0 OFFSET 1", 'b', 'bid'), array_merge(array($module, $delta, $theme_key), $rids));
