Cosmetic cleanups in initial catalog data.

Cosmetic cleanups in initial catalog data.

Write ',' and ';' for typdelim values instead of the obscurantist
ASCII octal equivalents.  Not sure why anybody ever thought the
latter were better; maybe it had something to do with lack of
a better quoting convention, twenty-plus years ago?

Reassign a couple of high-numbered OIDs that were left in during
yesterday's mad rush to commit stuff of uncertain internal
temperature.

The latter requires a catversion bump, though the former wouldn't
since the end-result catalog data is unchanged.
