On second thought, a catalog is overkill; it'd only be useful if the data
could change after initdb, which this data surely cannot. The right way
to expose such info to SQL is with a set-returning function reading a
constant table in the C code, a la pg_get_keywords(). That way takes a
whole lot less infrastructure and is just as useful to SQL code.
[ wanders away wondering about a debug mode in which we actually validate
OIDs inserted into such columns... ]
