I attach complete patch which renames following binaries
createdb createlang createuser dropdb droplang dropuser clusterdb
vacuumdb reindexdb
to
pg_createdb pg_createlang pg_createuser pg_dropdb pg_droplang
pg_dropuser pg_clusterdb pg_vacuumdb pg_reindexdb
Symlinks (or copy on win32) are created for backward compatibility.
This renaming was discussed there:
http://archives.postgresql.org/pgsql-hackers/2007-06/msg00145.php
I create also separate unified patch for documentation.
