Re: SRF question

yes, parseTypeString() seems to be the way.

I've found parseTypeString() in plpgsql.so... would it be ok to call dlopen('plpgsql.so', ...) from my C code to access this function or is there some other method I sould use?

thanks tom.

A SELECT seems like the hard way.  Look into parse_type.c for some
routines that might help.  Offhand parseTypeString() is probably your
best bet.

I believe you can just set it to NIL, since you are only interested in
composite types.
