Re: pl/pgsql how to return multiple values from a function

I found following notes on news list with Google. And I have a try but it
still doesn't work. The problem is pl/pgsql complains that function of col1
is not found. My postgres is v7.3.2. Please help. Thank you in advance.

Sure you can, I wouldn't nessessarily recommend it. rec_tmp must be a
table somewhere so it can be a 'type', you get the values from the record
by using syntaxt like SELECT col1(teste_tmp(1)), col2(teste_tmp(1)),
col3(teste_tmp(1));

You could also return a CURSOR but I've never tried that (I access
PostgreSQL from perl's DBI which doesn't support a cursor return type).
