How can we avoid this error or make the cursor still working afterwards?

The other idea is to declare the function to return SETOF refcursor (or
have an OUT refcursor param), and return two refcursors open with the
different recordsets.

because casting fails. First FETCH was ok, and evaluating of next row
(which need second FETCH) was broken. When any statement in
transaction fail, you have to rollback current transaction.

The problem is, that the CAST function may be used in any SQL query,
since our software allows using a free SQL-query. The query itself
doesn't fail, because the syntax is correct.
The problem is that there may be other functions in a query that can
lead to a runtime error

The materialize shields the sort from the need to do mark/restore and
thereby allows it to perform its final merge pass on-the-fly; while the
