1. change palloc to malloc

   Nguyen Hai <nguyen_hai91@yahoo.com> — 2005-03-15T23:18:34Z

   Hi,
   
   Is it possible to convert palloc back to malloc?
   If so, what should I do to make the change?
   
   Many Thanks,
   Hai

   You can, but palloc is automatically freed at the end of a query, while
   malloc has to be freed in the code.  Why do you want to make the
   switch?

   Right. And it's definitely faster use palloc() than malloc(). I think
   the current code is really based on memory contexts and I'm sure that
   (strange:-) s/palloc/malloc/ is not enough.
