This PR reduces the dataset size in the transparent_decompression
test to make it finish in a more reasonable time. It also splits
the test and modifies queries that used now(). Due to the change
in dataset size the resulting diff is rather large but is mostly
row count changes in the plan but the actual plan shapes don't
change. In addition to those changes to some LATERAL queries
additional constraints have been added to reduce the number of
loops.
1. This commit introduces changes to existing plans due
to the addition of new chunks to metrics_ordered_idx.
2. Add tests for constraint aware appends on compressed
tables.
