We failed to pass down the query string to check_new_partition_bound, so that its attempts to provide error cursor positions were for naught; one must have the query string to get parser_errposition to do anything. Adjust its API to require a ParseState to be passed down. Also, improve the logic inside check_new_partition_bound so that the cursor points at the partition bound for the specific column causing the issue, when one can be identified. That part is also for naught if we can't determine the query position of the column with the problem. Improve transformPartitionBoundValue so that it makes sure that const-simplified partition expressions will be properly labeled with positions. In passing, skip calling evaluate_expr if the value is already a Const, which is surely the most common case.

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/.
