Обсуждение: Calling functions inside a function: behavior

Hi all,
   I wrote a function that call another functions, like this:

FUNCTION (...) AS '(...)BEGIN
PERFORM FUNCTION1();
PERFORM FUNCTION2();
(...)
END;' LANGUAGE 'PLPGSQL';
   The problem is that takes a long time to execute (I stoped after three 
days executing). To see who taking more time to execute, I modified each one 
to return the time of its execution. Then, a made a scrip like:

SELECT TIMESTAMP 'NOW';
SELECT FUNCTION1();
SELECT FUNCTION2(); (...)
SELECT TIMESTAMP 'NOW';
   and, for my surprise, it take minutes to run. I read the documentation 
and I didn't found any coment abou this behavior. Can anyone explain this?
   Thank you,
   Edipo Elder   [edipoelder@ig.com.br]

Cool, one more Brazilian in the list :)
I don't see any difference between calling the functions with a select
or a perform, except that with perform the return value is discarded.What version of PG are you running and what are
thosefunctions
 
written in (PL/pgSQL, PL/Tcl, PL/Perl)?Can you post a snippet of the functions here?
