I had a closer look at the tests failing with Firebird 3.0.4.33054 (x64):

bug_69356.phpt fails because FB doesn't support `SELECT expr;` queries;
apparently, a FROM clause would be required.

bug_71447.phpt fails because there are issues regarding comments with a
single quote.

bug_73234.phpt fails because FB doesn't support defining explicit
nullable columns, i.e.

  CREATE TABLE (id INT NULL)

is unsupported.  Removing the NULL let's the test proceed, but binding a
zero as PDO::PARAM_NULL apparently inserts `string(1) "0"` which looks
like a bug in the driver.
