Prevent stack overflow in query-type functions.

The tsquery, ltxtquery and query_int data types have a common ancestor.
Having acquired check_stack_depth() calls independently, each was
missing at least one call. Back-patch to 9.0 (all supported versions).

This is the main PostgreSQL git repository.
