Dimitri Fontaine 538464f078 Avoid operator is not unique errors.
When the intarray extension is installed our PostgreSQL catalog query fails
because we now have more than one operator solving smallint[] <@ smallint[].
It is easy to avoid that problem by casting to integer[], smallint being an
implementation detail here anyway.

Fix #532.
