Be aware that prairiedog and locust (unlike the rest of the buildfarm)
have compilers whose "bool" type is not 1 byte long; PG can't use that,
so we don't include <stdbool.h> on those platforms.
Looking at c.h, the problem seems to be that when we define our own bool
in the absence of a usable stdbool.h, we do so as a typedef and not a
macro. So pgtypeslib_extern.h ends up redefining it in that case, and
(this bit may be my fault: see d26a810eb) uses a different type to c.h
(char vs. unsigned char).
(stdbool.h is required by spec to do #define bool _Bool rather than a
typedef, hence the difference in behavior)
I'm no expert on the ECPG internals, but this doesn't look like an
exposed interface, so maybe it just shouldn't be trying to #define bool
at all and just rely on c.h (from postgres_fe.h) to declare the type?
