 179
 180 * MySQL 5.0.3 or later
 181 * PostgreSQL 8.3 or later

 185
 186 == Upgrading ==
 187 1.31 has several database changes since 1.30, and will not work without schema
 188 updates. Note that due to changes to some very large tables like the revision
 189 table, the schema update may take quite long (minutes on a medium sized site,
 190 many hours on a large site).
 191
 192 Don't forget to always back up your database before upgrading!
 193
 194 See the file UPGRADE for more detailed upgrade instructions, including
 195 important information when upgrading from versions prior to 1.11.
