Comment (by jarshwah):
Thanks for knocking this up. I just ran the the test suite on Oracle with
this patch:
1minute 53 seconds to create the first database
27 seconds to create the second database
(The cleanup/dropping databases is also heavily weighted against the first
database - I didn't measure but it would have been around 1 minute and 30
seconds respectively)
Without Patch:
2 minutes to create the first database
1 minute 35 seconds to create the second database.
About 1 minute is saved on the creation of the second database. I suspect
mssql will see similar improvements, so I'll tag manfre here incase he
wants to check it out.
I have done some measurements WRT Oracle and migrations but I abandoned
them. Querying for table_names, view_names, and constraints takes quite a
long time, and the results are never cached (clearing the cache wasn't as
straightforward as it could have been).

struggle with git apply x.patch like I did :P
