Interesting. I've always wondered whether the "debug_assertions" GUC
variable is worth the electrons it's printed on. If you are running
with asserts active, that variable actually slows things down, by
requiring an additional bool test for every Assert. I suppose the
motivation was to allow the same compiled executable to be used for both
assert-enabled and assert-disabled runs, but how many people really need
that capability?
