I noticed that plpgsql would allow assignment of a new value to a variable even when that variable is marked CONSTANT, if the variable is used as an output parameter in CALL or is a refcursor variable that OPEN assigns a new value to. Fix these oversights. In the CALL case, the check has to be done at runtime because we cannot know at parse time which parameters are OUT parameters. For OPEN, it seems best to likewise enforce at runtime because then we needn't throw error if the variable has a nonnull value (since OPEN will only try to overwrite a null value). Although this is surely a bug fix, no back-patch: it seems unlikely that anyone would thank us for breaking formerly-working code in minor releases.

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/.
