Обсуждение: pgsql: In pg_upgrade cross-version test, handle postfix operators.

In pg_upgrade cross-version test, handle postfix operators.

Commit 1ed6b895634ce0dc5fd4bd040e87252b32182cba eliminated support for
them, so drop them from regression databases before upgrading.  This is
necessary but not sufficient for testing v13 -> v14 upgrades.
