[COMMITTERS] pgsql: Fix inclusions of c.h from .h files.

Fix inclusions of c.h from .h files.

We have a project policy that every .c file should start by including
postgres.h, postgres_fe.h, or c.h as appropriate; and then there is no
need for any .h file to explicitly include any of these.  Fix a few
headers that were violating this policy by including c.h.
