pgsql: Fix DROP INDEX CONCURRENTLY IF EXISTS. - Mailing list pgsql-committers

Fix DROP INDEX CONCURRENTLY IF EXISTS.

This threw ERROR, not the expected NOTICE, if the index didn't exist.
The bug was actually visible in not-as-expected regression test output,
so somebody wasn't paying too close attention in commit
8cb53654dbdb4c386369eb988062d0bbb6de725e.
Per report from Brendan Byrd.
