Commit 964d01ae9 marked a lot of fields as read_write_ignore to stay consistent with what was dumped by the manually-maintained outfuncs.c code. However, it seems that a pretty fair number of those omissions were either flat-out oversights, or a shortcut taken because hand-written code seemed like it'd be too much trouble. Let's upgrade things where it seems to make sense to dump. To do this, we need to add support to gen_node_support.pl and outfuncs.c for variable-length arrays of Node pointers. That's pretty straightforward given the model of the existing code for arrays of scalars, but I found I needed to tighten the type-recognizing regexes in gen_node_support.pl. (As they stood, they mistook "foo **" for "foo *". Make sure they're all fully anchored to prevent additional problems.) The main thing left un-done here is that a lot of partitioning-related structs are still not dumped, because they are bare structs not Nodes. I'm not sure about the wisdom of that choice ... but changing it would be fairly invasive, so it probably requires more justification than just making planner node dumps more complete.

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/.
