14 -- SQL to create the initial tables for the MediaWiki database.

16 -- not have to run it by itself unless doing a manual install.
21 -- If possible, create tables as InnoDB to benefit from the
22 -- superior resiliency against crashes and ability to read
23 -- during writes (and write during reads!)
25 -- Only the 'searchindex' table requires MyISAM due to the

30 -- The MySQL table backend for MediaWiki currently uses
31 -- 14-character CHAR or VARCHAR fields to store timestamps.

33 -- text format of MySQL's TIMESTAMP fields.
35 -- Historically TIMESTAMP fields were used, but abandoned
36 -- in early 2002 after a lot of trouble with the fields
