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 Carsten Kropf Am 22.03.2010 um 13:18 schrieb Tom Lane:
