Based on the extensive feedback here, as well as other information from other
websites found since asking here, I've decided that I'm still, very happily,
a PG user.
No significant issues to date - PG has "just worked" for me for 5 years now,
and the frustrating limitations (EG: alter table drop field, row size limits)
functionally disappeared some time ago. It's always good to reevaluate where
you are now to make sure you're not doing something stupid.
Replication is the only thing that remains, and there appears to be
commercially viable solutions for that, as well, though we've not yet
implemented it. We're still in a very heavy product development phase, and we
have a pretty good backup solution.
When will PG replication come ready "out of the box" with the RH RPMs?
Anyway, once again, Postgres is my friend...
