I usually create new databases with an explicit owner which is the application
user that is used by the application to connect to the database.
I recently noticed when I do the following:

Alberto Cabello Sánchez, 08.04.2014 13:05:
But I would have expected the owner of the database to be the owner of any
object that is created during database initialization.
Do I have a wrong assumption here?

the name fields after the first load. By that point is was on

it's just cumbersome workaround - and not real solution,

The other part of the problem is that you're using transactions for
something other than transactional integrity. You're batching up
transactions in order to improve performance. That's certainly
possible, but you're using the database oddly, so you can't expect
