pgsql-server: Dept.

Log Message:
-----------
Dept. of second thoughts: it'd be a good idea to flush buffers
during replay of CREATE DATABASE as well as the first time around.
Else it's possible that the copy operation will copy obsolete blocks.
We are still a long way from guaranteeing anything about using a
recently-written database as a CREATE template, but this seems needed
to ensure the existing behavior holds up during replay.
