Check that if we generate a call to copy, compare, write, or read a specific node type, that node type does have the appropriate support function. (This doesn't protect against trying to invoke nonexistent code when considering generic field types such as "Node *", but it seems like a useful check anyway.) Check that array_size() refers to a field appearing earlier in the struct. Aside from catching obvious errors like a misspelled field name, this protects against a more subtle mistake: if the size field appears later in the struct than the array field, then compare and read functions would misbehave. There is actually exactly that situation in PlannerInfo, but it's okay since we do not need compare or read functionality for that (today anyway).

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/.
