/**
 * @file
 * All incremental database updates performed between Drupal releases.
 *
 * For all updates after 147, please use the following syntax:
 *
 * function update_N() {
 *   $ret = array();
 *
 *   switch ($GLOBALS['db_type']) {
 *     case 'pgsql':
 *       // PostgreSQL code goes here
 *       break;
 *     case 'mysql':
 *     case 'mysqli':
 *       // MySQL code goes here
 *       break;
 *   }
 *
 *   return $ret;
 * }
 *
 *
 * A quick guide to mysql2postgres conversion. Usually (but not allways!) you will use following sql statements:
 *
 * - Adding a key (an index):
 * mysql: ALTER TABLE {$table} ADD KEY $column ($column)
 * pgsql: CREATE INDEX {$table}_$column_idx ON {$table}($column)  // Please note the _idx "extension"
 *
 * - Adding a primary key:
 * mysql: ALTER TABLE {$table} ADD PRIMARY KEY $column ($column)
 * pgsql: ALTER TABLE {$table} ADD PRIMARY KEY ($column)
 *
 * - Dropping a primary key:
 * mysql: ALTER TABLE {$table} DROP PRIMARY KEY
 * pgsql: ALTER TABLE {$table} DROP CONSTRAINT {$table}_pkey
 *
 * - Dropping a column:
 * mysql: ALTER TABLE {$table} DROP $column
 * pgsql: ALTER TABLE {$table} RENAME $column TO $column_old  // For compatibility reasons we don't drop columns but rename them
 *
 * - Dropping an index:
 * mysql: ALTER TABLE {$table} DROP INDEX $index
 * pgsql: DROP INDEX {$table}_$column_idx                            // When index was defined by CREATE INDEX
 * pgsql: ALTER TABLE {$table} DROP CONSTRAINT {$table}_$column_key  // In case of UNIQUE($column)
 *
 * - Adding a column: (an example)
 * mysql: $ret = update_sql("ALTER TABLE {vocabulary} ADD tags tinyint(3) unsigned default '0' NOT NULL");
 * pgsql: db_add_column($ret, 'vocabulary', 'tags', 'smallint', array('default' => 0, 'not null' => TRUE));
 *
 * - Changing a column: (an example):
 * mysql: $ret[] = update_sql("ALTER TABLE {locales_source} CHANGE location location varchar(255) NOT NULL default ''");
 * pgsql: db_change_column($ret, 'locales_source', 'location', 'location', 'varchar(255)', array('not null' => TRUE, 'default' => "''"));
 *
