-- SQL to create the initial tables for the MediaWiki database.
-- This is read and executed by the install script; you should
-- not have to run it by itself unless doing a manual install.
-- This is the PostgreSQL version.
-- For information about each table, please see the notes in maintenance/tables.sql
-- Please make sure all dollar-quoting uses $mw$ at the start of the line
-- TODO: Change CHAR/SMALLINT to BOOL (still used in a non-bool fashion in PHP code)
