Thanks a lot,
basically I looked inside these functions in parse_type.c and did not find an
"easy to use" application here. So I considered trying to construct the
required arguments passed to typenameType. However, during the development, I
found the following function:
Oid
TypenameGetTypid(const char *typname)
which does indeed do the lookup of my particular type in the cache and system
catalog tables. Thanks a lot for the hint!
Best regards
