These changes should generally improve correctness/maintainability. A nice side benefit is that several kilobytes move from initialized data to text segment, allowing them to be shared across processes and probably reducing copy-on-write overhead while forking a new backend. Unfortunately this doesn't seem to help libpq in the same way (at least not when it's compiled with -fpic on x86_64), but we can hope the linker at least collects all nominally-const data together even if it's not actually part of the text segment. Also, make pg_encname_tbl[] static in encnames.c, since there seems no very good reason for any other code to use it; per a suggestion from Wim Lewis, who independently submitted a patch that was mostly a subset of this one.

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: http://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. Changes between all PostgreSQL releases are recorded in the file HISTORY. 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 http://www.postgresql.org/download/. For more information look at our web site located at http://www.postgresql.org/.
