The initial version of gen_node_support.pl manually excluded most utility statement node types from having out/read support, and also some raw-parse-tree-only node types. That was mostly to keep the output comparable to the old hand-maintained code. We'd like to have out/read support for utility statements, for debugging purposes and so that they can be included in new-style SQL functions; so it's time to lift that restriction. Most if not all of the previously-excluded raw-parse-tree-only node types can appear in expression subtrees of utility statements, so they have to be handled too. We don't quite have full read support yet; certain custom_read_write node types need to have their handwritten read functions implemented before that will work. Doing this allows us to drop the previous hack in _outQuery to not dump the utilityStmt field in most cases, which means we no longer need manually-maintained out/read functions for Query, so get rid of those in favor of auto-generating them. Fix a couple of omissions in gen_node_support.pl that are exposed through having to handle more node types. catversion bump forced because somebody was sloppy about the field order in the manually-maintained Query out/read functions. (Committers should note that almost all changes in parsenodes.h are now grounds for a catversion bump.) |

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/.
