Thread: PL/pgSQL Return statements

PL/pgSQL Return statements

From

Hello,
I am currently trying to upgrade PostgreSQL from 8.0 to 8.1 on our development machine and have run into a problem with RETURN VOID; statements in PL/pgSQL functions that have a return type of void.
I'm getting errors like the following:
 
ERROR:  RETURN cannot have a parameter in function returning void at or near "VOID" at character 2983.
 
Does this mean I must edit every function that is declared with RETURNS VOID and remove the RETURN VOID; statement from the body?
 
I did a pg_dumpall using the 8.1 libraries on the 8.0 database and this made no difference.
 
Thanks in advance,
regards
Donald Fraser

Yup.  That was never correct code, but plpgsql used to completely ignore
anything after RETURN in a function declared to return VOID.  Which
surprised enough people that we changed it ...
