Originally we didn't bother to mark FuncExprs with any indication whether VARIADIC had been given in the source text, because there didn't seem to be any need for it at runtime. However, because we cannot fold a VARIADIC ANY function's arguments into an array (since they're not necessarily all the same type), we do actually need that information at runtime if VARIADIC ANY functions are to respond unsurprisingly to use of the VARIADIC keyword. Add the missing field, and also fix ruleutils.c so that VARIADIC ANY function calls are dumped properly. Extracted from a larger patch that also fixes concat() and format() (the only two extant VARIADIC ANY functions) to behave properly when VARIADIC is specified. This portion seems appropriate to review and commit separately. Pavel Stehule |

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: http://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. Changes between all PostgreSQL releases are recorded in the file HISTORY. 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 http://www.postgresql.org/download/. For more information look at our web site located at http://www.postgresql.org/.
