What do you mean by transaction logging? Any relational DB has transaction logs.
OK, I can't really disagree about the replication although I'm forced
to wonder exactly how reliable it will be given that replication
really should have a solid model for relational integrity underlying

I find that autovacuum is *nearly* good enough and vacuum can be scheduled.
Oh, and I don't see anything better on reclaiming 'old' space in mysql.

Hmm. We've agreed to disagree on the steaming pile of cack that mysql
calls authentication before, haven't we? GRANT/REVOKE work pretty well
the same on every other engine. Network level access is and should be
a different thing (imho).

Hmmm. Let me think. Yup. I've been using mysql on and off since early
98. I've always expected it to act like a database and I've always
been bitten when it doesn't.

Now we're close to agreement. If what you want is a fast storage
mechanism with an SQL-ish model for accessing that data then mysql
isn't a terrible choice.
However, MySQL AB keep trying to sell it as an enterprise level RDMS
and it ain't.
