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.

    if (pos->type == TokenType::Minus)
    {
        Pos begin = pos;
        if (ParserCastOperator().parse(pos, node, expected))
            return true;
        pos = begin;
        if (ParserLiteral().parse(pos, node, expected))
            return true;
        pos = begin;
    }
    return operator_parser.parse(pos, node, expected);
}
bool ParserCastExpression::parseImpl(Pos & pos, ASTPtr & node, Expected & expected)
