Per the code coverage report, the existing regression tests did not exercice some a couple important BRIN minmax-multi code paths. - The tests focused on testing planning with a range of scan key strategies, but not the execution. Fixed by adding queries that actually test query execution for both equality and inequality. - All tests created indexes after inserting data, but this only exercises the CREATE INDEX strategy that sees all values at once, not incremental summary updates. The new tests flip the order and create the index before adding data. - The assert check(s) validating correctness of expanded ranges were present only in the "union" code path, which is not covered by regression tests at all (as it requires concurrency etc.). Fixed by adding the asserts to a couple more places. Reviewed-by: Heikki Linnakangas Discussion: https://postgr.es/m/57020b2e-d9c9-9bc7-4892-b36d9bb07563%40enterprisedb.com

PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
