Provide a developer-only GUC allow_in_place_tablespaces, disabled by default. When enabled, tablespaces can be created with an empty LOCATION string, meaning that they should be created as a directory directly beneath pg_tblspc. This can be used for new testing scenarios, in a follow-up patch. Not intended for end-user usage, since it might confuse backup tools that expect symlinks.
