These define the OIDs used in the database itself.

These define the numbers used by ecpg to define its datatypes.

No. Well not really. ECPG does have a few conversion routines it needs
internally, but a full fledged mapping doesn't really exist. But then
you probably don't need one because the client-server conversation is
done in ascii most of the time and ecpg takes care of all the
conversions needed.
