Tom Lane 3922f10646 Fix bogus logic for combining range-partitioned columns during pruning.
gen_prune_steps_from_opexps's notion of how to do this was overly
complicated and underly correct.

Per discussion of a report from Alan Jackson (though this fixes only one
aspect of that problem).  Back-patch to v11 where this code came in.

database management system.

PostgreSQL is an advanced object-relational database management system

and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

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
