Subject: gnu: PostgreSQL: Permit loading plugins from symlink unions again.

...this fixes a regression since 49b350fafc2c3 where the patch to disable
symlink resolving went missing from versions < 14.

* gnu/packages/databases.scm (postgresql-13/replacement): New variable.
(postgresql-13)[replacement]: New field.
(postgresql-11)[source](patches): Add 'postgresql-disable-resolve_symlinks.patch'.
