Yes, `postgres.h` not the first include in the file. Actually I can
not include it before `locale` on Linux, otherwise I get the following
error:
In file included from /usr/bin/../lib/gcc/x86_64-linux-gnu/10/../../../../include/c++/10/locale:41:

The header `locale` is a dependency of my string handler, that in turn
includes quite a lot of other headers.
For PostgreSQL 13.x and earlier I could include `postgres.h` last, and
it worked on all platforms.
I can try and isolate my PostgreSQL calls and wrap them in some more
"pure" code, to avoid other includes. Or is there anything else I can
try?
All the best,
