Some not so long time ago, it was discussed to look into taking
stdbool.h into use. The reason was that third-party libraries (perl?,
ldap?, postgis?) are increasingly doing so, and having incompatible
definitions of bool could/does create a mess.

Here is a patch set that aims to accomplish that. On the way there, it
cleans up various loose and weird uses of bool and proposes a way to
ensure that the system catalog structs get a 1-byte bool even if the
"standard" bool is not.

I have done a fair amount of testing on this, including a hand-rigged
setup where _Bool is not 1 byte. But obviously, more and wider testing
would be very useful.
