fix ZIC dependency on postgres.h

Zdenek Kotala <Zdenek.Kotala@Sun.COM> writes:

I attached patch which removes dependency on postgres.h during ZIC
compilation.

I consider it poor style to have an include file (particularly one
that's fairly widely used, like pgtime.h) including any of postgres.h
postgres_fe.h or c.h. That's pre-empting a decision that needs to be
made on a per-c-file basis. So I fixed it as attached, instead.
