   1 -- SQL to create the initial tables for the MediaWiki database.
   2 -- This is read and executed by the install script; you should
   3 -- not have to run it by itself unless doing a manual install.
   4 -- This is the PostgreSQL version.
   5 -- For information about each table, please see the notes in maintenance/tables.sql
   6 -- Please make sure all dollar-quoting uses $mw$ at the start of the line
   7 -- We can't use SERIAL everywhere: the sequence names are hard-coded into the PHP
   8 -- TODO: Change CHAR to BOOL, TEXT to CIDR, allow custom schema
