I'm pretty sure I'm to blame for both of those special cases. The genesis
of both is that we are including these headers from externally-generated
.c files, and it seemed like modifying the .c files would be a bigger
problem than violating the policy. I am not sure if I hold that position
anymore for the regexp library; our copy has diverged substantially from
Tcl's anyway. It's still an issue for Snowball, because those .c files
are actually machine-generated by a Snowball-to-C compiler. We haven't
modified them and probably shouldn't.
If we don't change the code layout, we should probably at least add
comments near these postgres.h inclusions explaining why they're violating
policy.
