Michael Paquier 5bde1651bb Switch function current_schema[s]() to be parallel-unsafe 
When invoked for the first time in a session, current_schema() and
current_schemas() can finish by creating a temporary schema.  Currently
those functions are parallel-safe, however if for a reason or another
they get launched across multiple parallel workers, they would fail when
attempting to create a temporary schema as temporary contexts are not
supported in this case.

The original issue has been spotted by buildfarm members crake and
lapwing, after commit c5660e0 has introduced the first regression tests
based on current_schema() in the tree.  After that, 396676b has
introduced a workaround to avoid parallel plans but that was not
completely right either.

Catversion is bumped.
