Re: Determining the OID of a certain type

[Carsten Kropf <ckropf2@xxxxxxxxx>]

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

Starting from what?

For built-in types it's usual practice to use the #define from
pg_type.h, if there is one.  If you have a string name for the type,
there's a parser function to derive an OID, which I forget the name
of but it's probably in parse_type.c.
