Subject: [PATCH] Include c.h instead of postgres.h in
 src/port/*p{read,write}*.c

Frontend code shouldn't include postgres.h. Some files in src/port/ need to
include postgres.h/postgres_fe.h, but these files don't.

Discussion: https://postgr.es/m/20220915022626.5xx3ccgkzpkqw5mq@awork3.anarazel.de
Backpatch: 12-, where 3fd2a7932ef introduced (some) of these files
