Обсуждение: fix ZIC dependency on postgres.h

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

It was discussed there:

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.
