[Qgis-user] Not editable Layer

[L.W.]

Hi,

after a restart of QGIS I can not edit a postgis layer anymore, I used
it a bunch of weeks without problems.

If I add this layer again to the project, than I can.

But I can not replace the new against the old one because of a lot of
relations to other layers.

I can not see any log entry.

A primary key is available.

Regards
