Thread: pgsql: Add missing #include.

Add missing #include.

Commit 31400a673 and siblings added a check_stack_depth() call in
contrib/intarray/_int_bool.c, but neglected to note that in our oldest
branches that file didn't have the #include that defines that function.
This results in a fortunately-harmless compiler warning.  Per buildfarm.
