There's a reason why that variable is a superuser-only setting: you're
supposed to have some clue what you're doing when you change it ;-)
If you need more stack space, what you generally have to do is adjust
the ulimit setting that the postmaster is started under. You can set
max_stack_depth up to a few hundred K less than the postmaster's
ulimit -s setting, but not more.
(We wouldn't even have the variable if there were a sufficiently
portable way to find out the ulimit stack depth automatically, but
there's not one that I know of.)
