Executable settings like `max_command_execution_time` or `command_termination_timeout` cannot be set for `executable()` table function at all. Which means that the hardcoded values will be used.
I suggest to add it to executable function definition.
The simplest way is:
```
SELECT * FROM executable('<script name>', '<format>', (SET max_command_execution_time=100), (SELECT * FROM table))
```
As executable constructor already parses input `SELECT` statements anyway, adding `SET` statement there seems pretty logical.
Ideas? Any other better API?
I can implement that one.

        return ParserKeyword(op).ignore(pos, expected);
    }
    else
    {
        if (strlen(op) == pos->size() && 0 == memcmp(op, pos->begin, pos->size()))
        {
            ++pos;
            return true;
        }
        return false;
    }
}
