Oh, okay. I'm not intent on changing it, just was wondering what the
motivation was. What do you think of changing all the token symbols to
be FOO_P? (Or P_FOO, per your comment, but I'd just as soon leave alone
the ones that already have a suffix.)

Right at the moment we have half a dozen cases where they leak past the
parser, e.g. TransactionStmt. I've been intending to clean that up.
I concur that we don't want anything past parse analysis to depend on
token values, since they change anytime the keyword set changes.

I'd settle for local consistency: if we need prefixes/suffixes on some
of the datetime field names, let's make all of them have one. But I
don't feel compelled to cause a flag day over the whole source tree ;-).
At least not all at once.
