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.

    ParserKeyword s_not("NOT");
    ParserKeyword s_between("BETWEEN");
    ParserKeyword s_and("AND");
    ASTPtr subject;
    ASTPtr left;
    ASTPtr right;
    if (!elem_parser.parse(pos, subject, expected))
        return false;
    bool negative = s_not.ignore(pos, expected);
    if (!s_between.ignore(pos, expected))
    {
        if (negative)
            --pos;
        
        node = subject;
    }
    else
    {
        if (!elem_parser.parse(pos, left, expected))
            return false;
