Not sure I completely understand your question, but here is an quick
explanation of pgAdmin's use of connections.
Behavior depends on the window.
The main window (aka the browser window) will have as many connections
as necessary. You double-click to connect to a server : you'll have a
connection to the maintenance database of this server and a connection
to the last database you were connected to (if you choose this option in
the Options window and if you were connected to another database than
the maintenance one). Then, you have a connection to every database you
see without a red cross. You can close a connection with the contextual
menu of a database. If you don't, all connection will be closed when you
quit the app.
The query tool opens a connection to the database you were connected to
when you clicked on the query tool button (or chose the query tool item
in the menu). If you choose another connection in the combobox of the
toolbar, it will open a new connection without closing the first ones.
They will all be closed when you will quit the query tool.
The status window opens a connection to the maintenance database
(usually postgres) of the server you were connected to when you chose
the Status window item in the menu. In 1.10, you can select another
database for the lock report so that we can show the locked relations'
names (which obviously opens another connection to this database). If
you change this connection, it closes the other one but keeps the
connection to the maintenance database (as it is needed for the other
report).
When you dump or restore a database, it will launch pg_dump or
pg_restore. They will open their own connection to the appropriate database.
There are other tools I probably forgot (the configuration ones for
example), but they are less important.
