Subject: At present, dates are put into a dump in the format specified by the
X-Git-Tag: REL7_4_BETA1~886
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=cf4cee1b17d71f59efb0b47c79357e102f542257;p=postgresql

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.
