Make heap desc routines that output status bit as arrays of constants avoid outputting array literals that contain superfluous punctuation characters that complicate parsing the output. Also make sure that no heap desc routine repeats the same key name (at the same nesting level), for the same reason. Arguably, these were both oversights in commit 7d8219a4. In passing, make the desc output code (which covers Heap's DELETE, UPDATE, HOT_UPDATE, LOCK, and LOCK_UPDATED record types) consistent in terms of the output order of each field. This order also matches WAL record struct order. Heap's DELETE desc output now shows the record's xmax field for the first time (just like UPDATE/HOT_UPDATE records).

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.
