Error: cannot mix different types of client data

Houston, we have a problem.
Using 1.15 dev latest pull from git.

Steps:
1. connect to postgresql server
2. select a database but the wrong one (deliberate misstep)
3. open query builder and enter an sql statement referring to another db
4. error, no relation 'xxxx' exists, ok
5. QB menu bar offers dropdown which contains name of currently 
connected db and 'new connection'
6. select 'new connection', dialog box appears
7. database list offers the db you really need, select it
8. OK, crash.

If this is a contextually illegal request, probably best that the user 
is prevented from hitting the error.

Workaround is easy, select the right db to begin with.
