Recent additions to ParseFuncOrColumn to make it reject non-procedure functions in CALL were neither adequate nor documented. Reorganize the code to ensure uniform results for all the cases that should be rejected. Also, use ERRCODE_WRONG_OBJECT_TYPE for this case as well as the converse case of a procedure in a non-CALL context. The original coding used ERRCODE_UNDEFINED_FUNCTION which seems wrong, and is certainly inconsistent with the adjacent wrong-kind-of-routine errors. This reorganization also causes the checks for aggregate decoration with a non-aggregate function to be made in the FUNCDETAIL_COERCION case; that they were not is a long-standing oversight.

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/.
