Since 7c079d7, partition bounds are able to use generalized expression syntax when processed, treating "minvalue" and "maxvalue" as specific cases as they get passed down for transformation as a column references. The checks for infinite bounds in range expressions have been lax though, causing crashes when trying to use column reference names with more than one field. Here is an example causing a crash: CREATE TABLE list_parted (a int) PARTITION BY LIST (a); CREATE TABLE part_list_crash PARTITION OF list_parted FOR VALUES IN (somename.somename); Note that the creation of the second relation should fail as partition bounds cannot have column references in their expressions, so when finding an expression which does not match the expected infinite bounds, then this commit lets the generic transformation machinery check after it. The error message generated in this case references as well a missing RTE, which is confusing. This problem will be treated separately as it impacts as well default expressions for some time, and for now only the cases where a crash can happen are fixed. While on it, extend the set of regression tests in place for list partition bounds and add an extra set for range partition bounds.

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. 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/.
