Re: Create database bug in 8.1.3 ? -> solved

Hi Dough,
Thank you for your answer.
Now the reasons for using template0 DB are pretty clear (there a mini test-case
Of this in the mail you have just answered;)).

Thanks again.

Regards. Milen

The reason is this:  any extra stuff that your database inherited from template1 (or whatever template you used) will
be
dumped out as part of your database.  There is no way to for pg_dump to tell what parts came from template1 and what
parts were added afterward, so it bases its dump on template0, which is a minimal database.  If you based your restored
database on template1, you would get collisions as the restore tried to add objects that were already there from
template1.

Make sense?
