This new function extracts common code from PrepareQuery() and exec_parse_message(). It is then exactly analogous to the existing pg_analyze_and_rewrite_fixedparams() and pg_analyze_and_rewrite_withcb(). To unify these two code paths, this makes PrepareQuery() now subject to log_parser_stats. Also, both paths now invoke TRACE_POSTGRESQL_QUERY_REWRITE_START(). PrepareQuery() no longer checks whether a utility statement was specified. The grammar doesn't allow that anyway, and exec_parse_message() supports it, so restricting it doesn't seem necessary. This also adds QueryEnvironment support to the *varparams functions, for consistency with its cousins, even though it is not used right now.

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/.
