Fixes for 3 bugs in pg_dump - Mailing list pgsql-patches

This patch fixes the following bugs:

* pg_dump --clean against a pre-7.3 server output drop commands in the
form: DROP "".foo; .  These will now all be output as: DROP public.foo;

* If you use ALTER USER to set user params on the cluster owner user,
these would not be dumped.  This patch will now dump ALTER USER commands
for the cluster owner.  If the -S command line switch is used to specify
a superuser, then the cluster owner ALTER USER commands will be dumped
for that user instead.

* The DateStyle and search_path GUC variables must not be quoted when
dumped.
