Hello everyone,
Thank you for bringing to attention the regression caused by the fix for
GEOT-7248. Part of the purpose of this fix was actually to cover the
case of multiple columns, which were in previous version not handled
properly either. There was indeed no exception, but the count was not
properly being calculated (because only one column was part of the
'distinct' operation, the count could be underestimated). The
problematic part of the fix is that this use case was not actually added
to the test coverage for which I apologize. Doing distinct on multiple
columns is not supported by all database systems, such as postgres. I
will need another approach for this case.
I will reopen the issue and provide a new fix with test coverage for
postgres shortly.
Kind Regards
Niels
