Subject: Unsupported feature F867: WITH TIES

Actually we don't support the SQL feature F867 "FETCH FIRST clause: WITH
TIES option". On the other side we support the window function "rank()"
which acts like the "WITH TIES option". My questions are: Is it hard to
implement the "WITH TIES option"? Are there plans for a realization /
how do we decide in general what to do next? Differs the semantic of the
"WITH TIES option" significantly from the "rank()" window function or
can we treat it as some kind of 'syntactical sugar'?
Regards, Jürgen Purtz
