Hi Internals, There are bugs #79276 <https://bugs.php.net/bug.php?id=79276> and #80340 <https://bugs.php.net/bug.php?id=80340> where PDO parses valid PostgreSQL statements incorrectly because it uses MySQL grammar for all statements regardless of the underlying platform.
I submitted pull request #6410 <https://github.com/php/php-src/pull/6410> which enables extensions to opt-in to MySQL-specific syntax (since it's not standard). Currently only `pdo_mysql` uses it. As Christoph Becker suggested, I'm bringing it here for discussion. Technically, it may be a BC break since there may exist PDO-based extensions outside the PHP repository that rely on compatibility with the MySQL syntax. Are there known extensions like this? Would this change be acceptable in one of the next minor releases? Regards, Sergei Morozov
