Previous message was sent before I finished it completely;)

Just produced a testcase where TSQLDBLibraryLoader is too late. Create new
app, drop TPQConnection, fill in all needed, save project, drop a
TSQLDBLibraryLoader on the form, enter PostGreSQL in ConnectionType, set
enabled true and TPQConnection.Connected:=true. Run program:
"Exception=Error reading SQLDBLibraryLoader1.ConnectionType:
SQLDBLibraryLoader1 : This operation is not allowed while the datatabase is
loaded" Reason: TPQConnection was already streamed and connection made with
the default lib.
