Thank you very much for your help. In V1 function calling convention, there are micros like PG_RETURN_TEXT_P and so on. Most of them are used to return values of the built-in datatypes. If I want the XXX_in function (for my own data type) to return a pointer to a particular structure, what micro should I use? i.e., how should I organize the return value? Thank you and wish you and everybody a merry Christmas.
