Default extension for sql scripts

Hi

If I save a sql script from the query window, shouldn't ".sql" be added
automatically
to the filename? It isn't added on osx as I just noticed - which got me
wondering
if it is added on other platforms. So - how are things on win32 or linux?

On a related note - Does it work on windows to double-click  a saved query,
and have pgadmin3 start _and_ open the query in a query window? I'd like
to add the feature to the osx version. My last Info.plist update was the
first
step for that - pgadmin now even opens when double-clicking the query,
but it doesn't open the query itself. Of course, this only works if the file
is named .sql, which is the reason for my first question.

greetings, Florian Pflug
