There is no might -- if you upgraded from RHEL 7 to RHEL 8 without
doing a reindex or a dump/reload there, you are pretty much guaranteed
to have corrupt text indexes from that. Regardless of PostgreSQL
versions, this was about the RHEL upgrade not the Postgres one.

This indicates you may have more than one problem.
But that doesn't mean it's not both, sadly.
