#
# This file implements tests for JOINs that use Bloom filters.
#
# The test case output is (mostly) all generated by PostgreSQL 14. This
# test module was created as follows:
#
# 1. Run a TCL script (included at the bottom of this file) that
# generates an input script for "psql" that will run man
# diverse tests on joins.
#
# 2. Run the script from step (1) through psql and collect the
# output.
#
# 3. Make a few minor global search-and-replace operations to convert
# the psql output into a form suitable for this test module.
#
# 4. Add this header, and the script content at the footer.
