Ticket #930 (closed bug: fixed)
SPIT does allow to connect to PostGIS
In SPIT I have setup the connection. The "Test Connect" says: "Connection to <database name here> was successfull". However, the "Connect" button in SPIT is greyed-out, inactive.
The same connection setup that SPIT refuses to use works OK for "Add a PostGIS Layer" dialog.
If in SPIT I choose a shapefile and press OK anyway, even though it seems I'm not connected (the "Connect" button is greyed-out all the time) and press OK, SPIT segfaults like described in the bug #865 (reported 2 months ago).
