Log Message:
-- Re-implemented the join pushdown optimization phase
(due to incorrect rewrites).
o The special equi-join operator working on unique column
names now incorporates for each operand a projection.
Based on this projection we can now always maintain the
correct schema and push the join even through renaming
projections.
The old variant did in some cases 'forget' from which
operand of an equi-join columns with the same name stem
from.
o The new equi-join pushdown phase is a lot more effective
than the old one and thus generates very wide relations
(where a large number of columns can be pruned afterwards).
Placing a projection pushdown phase (icols optimization)
afterwards allows us to map the resulting plans back to
bit-encoded column names without running out of column
bits.
