Fix segmentation fault when doing top k queries #152

Closed Dtenwolde closed 1 month ago

Dtenwolde commented 1 month ago

Fixes https://github.com/cwida/duckpgq-extension/issues/46

This PR only fixes the segmentation fault users could get when trying top k queries with slightly incorrect syntax, such as the example query in the abovementioned issue.

We do not yet support TopK queries.
