This does not sound like a bug in PostgreSQL. It could be a problem
with the RPM, but I would guess it is more likely to be some
misunderstanding on your part about exactly what happened during the
RPM upgrade.
You could look at what RPM was installed and maybe see what pre and
post install scripts it runs, and try to figure it out that way. I
find it pretty hard to believe that an RPM install would have removed
the entire contents of the data directory, though. It might have done
things like move a modified config file out of the way and replace it
with a new version, which could lead you to an incorrect conclusion
about where the data directory used to be, but I doubt it just nuked
it from orbit.
As a side note, the current version of PostgreSQL 11 is PostgreSQL
11.16. That's about four years worth of bug fixes that you're missing.
Hopefully once you get the upgrade procedure sorted out you'll make a
point of upgrading more regularly, because we do fix quite a few bugs.
