I did not know, either, but would have been glad, had I found such info
a few weeks ago when I started digging into the pg source ;)
And while we are at it, how about some CFLAGS="-DOPTIMIZER_DEBUG"
sweetness for the debugging section in the Dev FAQ?
Are there any other macros that enable some more debug output? (Or is
there a place where all this has already been documented?)
Cheers,
Matthias
