Still lots of db connections being left open that crash the system before too long

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a new database from scratch
2. Add several tables and new fields to those tables, occasionally adding a new 
record to one of the tables
3. Add more new fields in the schema designer
4. Get a message saying 'FATAL: sorry, too many clients already' when you add 
another field.

What is the expected output? What do you see instead?
It looks as though we're still having an issue where db connections are being 
opened and not being closed again. It seems that the schema designer is the 
culprit (although of course there may be more than one element of the ORDS 
that's causing this).

This is using App 1.0.6 in Firefox.
