Fix logical decoding test to correctly check slot removal on standby.

MasaoFujii · MasaoFujii · commit aab422af95c3 · 2025-04-04T13:33:52.000+09:00
The regression test for logical decoding verifies whether a logical slot is correctly dropped on a standby when its associated database is dropped. However, the test mistakenly retrieved slot information from the primary instead of the standby, causing incorrect behavior. This commit fixes the issue by ensuring the test correctly checks the slot on the standby. Back-patch to all supported versions.
