> Hi there,
> 
> I just commited a larger change to the postgres provider.  Mostly it's
> refactoring, but it also contains some features.
> 
> You should now be able to use primary keys that are not numeric and even
> primary keys with more that one column should work (not sure how well the
> latter performs).
> 
> The handling of the GEOMETRY type was also changed - the geometry type is now
> specified in the layer uri and therefore the automatically generated subset
> string is not necessary anymore.  For empty tables you can select with geometry
> type to use.
> 
> Views still need numeric primary keys and those need to be selected when
> adding.
> 
> Please test and report.

>     [FEATURE][API] postgres provider refactoring:
>     - use m prefix for member variables and s prefix for class variables
>     - refactor QgsPostgresProvider::Conn and QgsPostgresConnection to
>       QgsPostgresConn
>     - put QgsColumnTypeThread into separate file
>     - use QgsPostgresConn in QgsPgSourceSelect
>     - cleaner abort of column type thread (e.g. remove unfinished columns from
>       selection list)
>     - [API] move QgsDbTableModel as QgsPgTableModel to provider
>     - [FEATURE] support for arbitrary key (including non-numeric and multi
>       column)
>     - [FEATURE][API] support for requesting a certain geometry type and/or srid
>       in QgsDataSourceURI
>      * no more explicit filter strings
>      * support for empty tables without gemetry_columns entry or GEOMETRY type.
