I'm using C interface. I'm a little confused regarding type enumerations/defines. There is set of OID defines in pg_type.h. But there is also file ecpgtype.h which contains enumeration ECPGttype. Is there any mapping between OID and ECPGttype? What are usecases of those types?

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.
