I've got low-level routines coded for interfacing predicate.c to SLRU
to handle old committed transactions, so that SSI can deal with
situations where a large number of transactions are run during the
lifetime of a single serializable transaction. I'm not actually
*using* these new functions yet, but that's what I do next. I would
love it if someone could review this commit and let me know whether
it looks generally sane.
