Lots of Warnings Upon Enabling and more warnings when trying to delete fields I've attached to validators

I'm getting the following warnings upon enabling. And though I'm able to create validators and assign fields to them, it produces even more warnings when I go to delete a field (and fails to delete it).

Upon Enabling the module I get...

and when trying to delete a field that I've attached to a validator, I get...

    * warning: pg_query() [function.pg-query]: Query failed: ERROR: syntax error at or near "," LINE 1: DELETE FROM f, av USING drupal_validation_api_fields AS f LE... ^ in /home/www/dev.merchant/html/includes/database.pgsql.inc on line 139.

Any suggestions, please?
