Hi Jürgen,

Thank you for you work on the PostgreSQL provider.

I have troubles with my views which worked before your refactoring. Now I can load the layer, but the geometry is not displayed. I can display the attribute table, but the primary key column is always NULL.

Do you have an idea why my views do not display and why the primary keys are NULL? I manually selected the pkey column as you described.

Thanks a lot,
Andreas

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.
