profile_checkboxes_update_1() breaks in Postgresql

I have updated this module on several sites with MySQL and Postgresql.
It breaks in Postgresql, because changing the checkboxes column to type and creating the delimiter column each creates a syntax error.

Here are the errors:
pg_query(): Query failed: ERROR: syntax error at or near "CHANGE" LINE 1: ALTER TABLE drupal_profile_checkboxes CHANGE COLUMN checkbox...
pg_query(): Query failed: ERROR: syntax error at or near "AFTER" LINE 1: ...ile_checkboxes ADD delimiter VARCHAR(10) NOT NULL AFTER type...
