I've just committed changes to the main development tree which allow
CASE statement handling for at least some cases of rules and views.
Still have trouble (crashes) with CASE statements involving mixing
columns from multiple tables during joins. But the single-table stuff
(and multi-table when the case statement is confined to a single table)
seems to work for my testing.
I have an update to the CASE regression test which has many more tests,
and will put it in the tree and on this list fairly soon (to get some
Oracle/etc testing of results).
