Re: [GENERAL] Re: Is PostgreSQL ready for mission criticalapplications?

I'd like to add one item to Mike Mascari's excellent and
helpful list:

Watch out for queries involving many result rows which include
functions or even aggregates in the select list:

--select f(x) into resulttable from bighugetable;

The way that postgres allocates/frees memory results in
potentially very large memory use by such queries. (Per-
row memory is not freed until the statement completes.)
My reading of the todo list is that this is a known bug
(or feature!).

BTW: Does anyone know if there are plans to fix this one soon?

We've used it successfully in a production environment (24 x

greatly improve your chances of success. The problems with
PostgreSQL can be avoided if you know, in advance, what to
