Sounds a little messy to me, and will certainly clutter up logs and things.

Yes, I think I agree.

I think the neatest place to set these will be in frmDatabase. Doing it
elsewhere will just be confusing. For most users, they can just leave them
alone, someone like yourself can just set & forget.
This would have to be stored in the registry - HKCU\Software\pgAdmin
II\Encodings\>Connection ID>\<Database Name>\[DataEncoding | systemEncoding]
- where <Connection ID> is of the form user|server|port as we using in the
Connections MRU list.
So, when a database is first connected, we read the relevant value and issue
a SET CLIENT_ENCODING. If pgDatabase->SystemEncoding gets updated, we write
to the registry, and issue another SET CLIENT_ENC...
That will work for System stuff. On the User/Data side, those queries *only*
come from frmSQLInput or a 'View Data' (iirc). For these types of query,
*if* we had a second connection to the database, then it could maintain it's
client encoding neatly as well. This would also have the advantage that
large queries would not be using the system connections and could
effectively give us a 'threaded' effect.
The downside would be that we would have extra connections (potentially
double). This could be minimised by only connecting on first use.
