 112
 113 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,

 117 The supported versions are:
 118
 119 * MySQL 5.0.3 or later
 120 * PostgreSQL 8.3 or later

 122 * Oracle 9.0.1 or later
 123 * Microsoft SQL Server 2005 (9.00.1399)
 124
 125 == Upgrading ==
 126 1.31 has several database changes since 1.30, and will not work without schema
 127 updates. Note that due to changes to some very large tables like the revision
 128 table, the schema update may take quite long (minutes on a medium sized site,
 129 many hours on a large site).
 130
 131 Don't forget to always back up your database before upgrading!
 132
 133 See the file UPGRADE for more detailed upgrade instructions, including
 134 important information when upgrading from versions prior to 1.11.
