#***********************************************************************
#
# This is a test case from content taken "from the wild". In this
# particular instance, the query was provided with permission by
# Elan Feingold on 2013-06-27. His message on the SQLite mailing list
# on that date reads:
#
#------------------------------------------------------------------------------
# > Can you send (1) the schema (2) the query that is giving problems, and (3)
# > the content of the sqlite_stat1 table after you have run ANALYZE? If you
# > can combine all of the above into a script, that would be great!
# >
# > If you send (1..3) above and you give us written permission to include the
# > query in our test suite, that would be off-the-chain terrific.
#
# Please find items 1..3 in this file: http://www.plexapp.com/elan/sqlite_bug.txt
#
# You have our permission to include the query in your test suite.
#
# Thanks for an amazing product.
#-----------------------------------------------------------------------------
#
# This test case merely creates the schema and populates SQLITE_STAT1 and
# SQLITE_STAT3 then runs an EXPLAIN QUERY PLAN to ensure that the right plan
# is discovered. This test case may need to be adjusted for future revisions
# of the query planner manage to select a better query plan. The query plan
# shown here is known to be very fast with the original data.
#
# This test should work the same with and without SQLITE_ENABLE_STAT3
