Instead of running a SQL script to create the standard conversion functions and pg_conversion entries, put those entries into the initial data in postgres.bki. This shaves a few percent off the runtime of initdb, and also allows accurate comments to be attached to the conversion functions; the previous script labeled them with machine-generated comments that were not quite right for multi-purpose conversion functions. Also, we can get rid of the duplicative Makefile and MSVC perl implementations of the generation code for that SQL script. A functional change is that these pg_proc and pg_conversion entries are now "pinned" by initdb. Leaving them unpinned was perhaps a good thing back while the conversions feature was under development, but there seems no valid reason for it now. Also, the conversion functions are now marked as immutable, where before they were volatile by virtue of lacking any explicit specification. That seems like it was just an oversight. To avoid using magic constants in pg_conversion.dat, extend genbki.pl to allow encoding names to be converted, much as it does for language, access method, etc names.

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/.
