Committed 0001.
To be honest, I don't really like either pg_transaction or pg_xact.
Neither name captures the fact that what we're really tracking here is
the transaction *status*. pg_xact is slightly worse because it's a
poor abbreviation for transaction, but I think the argument against
even pg_transaction is similar to the one Tom previously levied
against pg_logical - viz. "logical what?". The transaction themselves
are not stored in the directory, just the commit status. The fact
that commit status is saved is the source of the "c" in "clog".
