Hey guys, I just upgraded a DB from 12 to 13. In testing this seemed to go
well, but it seems like most of my queries are not using the indexes after
the upgrade, so everything is quite so.
Is there a general need to REINDEX after upgrading to 13, or might there
be another issue? The configuration parameters are the same as they were
persisted via pg_upgradecluster.
Did you also change or upgrade the distro, or modify the collation? (That's
an automatic need to rebuild indices.)
