Hello everyone, unfortunately there was no feedback to my first request, so here is the 2nd attempt. I think the problem should affect many people, right?
I have noticed the following: if I have read and write access (DML) to a PostgreSQL table, but no access to structure changes (DDL), then I can, for example, add new columns with the field calculator and fill them with results. Everything seems to run normally, I do not get a warning that I am not allowed to change the structure, the results generated in the field calculator are OK. After saving, all new columns including the data are gone. Can a corresponding preliminary check with warning be added here please? If a new column is explicitly added, a message appears whose content does not match the situation. "Could not add field 'Test' of type 'text'. Is the field name unique?“ A warning regarding missing authorizations for DB structure changes would be better. As far as I know, there is no QGIS ticket or change request(https://github.com/qgis/QGIS/issues) to improve the user guidance for these two cases. There are currently two relevant sections in the error messages(https://github.com/qgis/QGIS/blob/master/i18n/qgis_de.ts). <message> <location filename="../src/app/qgsattributetabledialog.cpp" line="969"/> <source>Failed to add field '%1' of type '%2'. Is the field name unique?</source> <translation>Could not add field '%1' of type '%2'. Is the field name unique?</translation> </message> <message> <location filename="../src/gui/vector/qgssourcefieldsproperties.cpp" line="286"/> <source>Failed to add field '%1' of type '%2'. Is the field name unique?</source> <translation>Could not add field '%1' of type '%2'. Is the field name unique?</translation> </message> Many thanks in advance. Mike Elstermann
