pgsql: Set indcheckxmin true when REINDEX fixes an invalid or not-ready - Mailing list pgsql-committers

Set indcheckxmin true when REINDEX fixes an invalid or not-ready index.

Per comment from Greg Stark, it's less clear that HOT chains don't conflict
with the index than it would be for a valid index.  So, let's preserve the
former behavior that indcheckxmin does get set when there are
potentially-broken HOT chains in this case.  This change does not cause any
pg_index update that wouldn't have happened anyway, so we're not
re-introducing the previous bug with pg_index updates, and surely the case
is not significant from a performance standpoint; so let's be as
conservative as possible.
