[HACKERS] Finding the correct type

[Thomas Hallgren]

I'm writing a UDT that takes a varchar argument that represents the name 
of a type. The caller may optionally qualify with a namespace, i.e. 
"pg_catalog.varchar", or "public.address". Is there a c-function 
somewhere that will return the pg_type that corresponds to the name 
(with respect to the current setting of search_path in case the name is 
unqualified)?
