I don't think we need "named constants", especially not
manually-maintained ones.  The thing that would help in pg_proc.h is for
numeric type OIDs to be replaced by type names.  We talked awhile back
about introducing some sort of preprocessing step that would allow doing
that --- ie, it would look into some precursor file for pg_type.h and
extract the appropriate OID automatically.  I'm too tired to go find the
thread right now, but it was mostly about building the long-DATA-lines
representation from something easier to edit.
