Обсуждение: plpgsql: debugging

Hi,

Searching Google I found a thread in July 2001 concerning the facilities 
for debugging plpgsql functions. The actual answer was: it should be 
improved.

What is the best way to debug a plpgsql function?

   This may not be the best way since its a bit
crude. Try using RAISE NOTICE every now then to
monitor the values of variables in the screen and
record it in log file.
   Example :
   RAISE NOTICE ''Initial value of variable =
%'',v_variable;
   /* Do some computation ... */
   RAISE NOTICE ''Value of variable after operation =
%'',v_variable;   


hope that helps,

ludwig
