Non-integer weight causing SQLSTATE[22P02] "Invalid text representation" with postgresql (works fine with mysql).

(This issue is not related to #1003788: PostgreSQL: PDOException:Invalid text representation when attempting to load an entity with a string or non-scalar ID).
see #7 for more serious cause of this issue.

On enabling the module PDOException: SQLSTATE[22P02] is raising making it not usable with postgresql. (auto entity label tab itself is not available)

Is this module only for mysql?
