[Qgis-developer] Error for postgres's provider when table(statement SELECT ) is outside public's schema

[Ricardo Filipe Soares Garcia da]

Hi Guiseppe, Luiz

I have to do some more checking to be sure, but I think this problem
is happening with both plugins. I haven't got a postgis database at
hand right now, but with my home testing set I was getting the same
error (something about cursor states lost) with both 'custom db query'
and 'rt sql layer' plugins.
I'll investigate later.

I didn't realize it might have something to do with the tables not
being in the 'public' schema until Luiz brought it up. All my testing
tables are indeed out of the 'public' schema.

If the problem is happening on both plugins, could this mean it is
something wrong with the underlying implementation?
I haven't copied code from the 'rt sql layer plugin', so it is likely
that the code is different. However, the QgsDataSourceURI.uri() must
be returning a similar value for it to work on both plugins...

Regarding the trac issues, sorry for the confusion. I am not very
knowledgeable about the main trac and the new plugins trac. Please
feel free to use the bug report in whatever way you see fit, be it
closing as invalid or whatever ;)
