At present, dates are put into a dump in the format specified by the

default datestyle.  This is not portable between installations.

This patch sets DATESTYLE to ISO at the start of a pg_dump, so that the
dates written into the dump will be restorable onto any database,
regardless of how its default datestyle is set.
