Обсуждение: pgsql: Fix PostgreSQL::Test aliasing for Perl v5.10.1.

Fix PostgreSQL::Test aliasing for Perl v5.10.1.

This Perl segfaults if a declaration of the to-be-aliased package
precedes the aliasing itself.  Per buildfarm members lapwing and wrasse.
Like commit 20911775de4ab7ac3ecc68bd714cb3ed0fd68b6a, back-patch to v10
(all supported versions).
