* PDO refactor * Automatic prefix when using the syntax `_tableName` * Uniformity: MySQL is now PDO::ATTR_EMULATE_PREPARES = false just like SQLite and PostgreSQL, with consequences such as only one statement per query * Use PDO methods exec(), query(), prepare() + execute() in a more efficient way * Remove auto-update SQL code for versions older than FreshRSS 1.5 (3 years old) * The name of the default category is set in PHP instead of in the DB (simplies SQL and allows changing the name according to the FreshRSS language) * Rename `->bd` to `->pdo` (less of a frenshism, and more informative) * Fix some requests, which were not compatible with MySQL prepared statements * Whitespace * Fix syntax for PostgreSQL sequences + MySQL install * Minor formatting * Fix lastInsertId for PostgreSQL * Use PHP 5.6+ const Take advantage of https://github.com/FreshRSS/FreshRSS/pull/2527 https://www.php.net/manual/en/migration56.new-features.php * A bit of forgotten PHP 5.6 simplification for cURL * Forgotten $s * Mini fix custom user config https://github.com/FreshRSS/FreshRSS/pull/2490/files#r326290346 * More work on install.php but not finished * install.php working * More cleaning of PDO in install * Even more simplification Take advantage of PDO->exec() to run multiple statements * Disallow changing the name of the default category https://github.com/FreshRSS/FreshRSS/pull/2522#discussion_r326967724
