@mosabua follow-up

aggregation-pushdown.enabled & topn-pushdown.enabled (and their corresponding session properties) are nowhere to be found in the documentation (except in some old release notes). Please consider adding them in the existing documentation.

Uff .. yeah .. we have to add them to a fragment that we include in all jdbc connectors .. maybe @jhlodin and team can help here

[mosabua]

Do we need to have a bit more about what a "complex expression" is somewhere?

@findepi, @Praveen2112 can you please help out here with wording?
It is important for the users to knwo the distinction between join-pushdown.enabled and join-pushdown.with-expressions
