The definition of c.h is bogus anyway.  You might think it contains
includes and defines to set up a portable C environment, which is what
the first half indeed does.

But then things like regproc, transaction ID types, IntArray, varlena,
bytea, oidvector, NameData, etc. do not belong there and should be moved
to postgres.h.
