# The focus of this file is testing the compound-SELECT merge
# optimization.  Or, in other words, making sure that all
# possible combinations of UNION, UNION ALL, EXCEPT, and
# INTERSECT work together with an ORDER BY clause (with or w/o
# explicit sort order and explicit collating secquites) and
# with and without optional LIMIT and OFFSET clauses.
