Thanks - patch committed. I made the following changes:

- Removed explicit support for 9.0 and below.
- Hid the default ACLs from the properties list for catalogs.
- Tidied up some of the SQL formatting

Open questions:

- We don't allow default ACLs to be specified when creating a schema
(neither does pgAdmin). Why not? Shouldn't we?

Hmm.. I don't see any reason, why we should not do it.

We have adopted that from pgAdmin III.

- We create new objects in 2 SQL statements, one that runs create.sql
and one that runs alter.sql to apply ACL, label options and more. I
strongly believe we need to push this into a single statement for all
object types, to ensure creation is completely atomic. Right now, you
can easily get an error by trying to set an unregistered security
label, which keeps the create dialogue open, however the object has
been successfully created.

Agree.

Even if they needed to be created from two, or more separate templates, they should ran together unless there are some statements, which require to run in separate transaction.
