Date arithmetic INTERVAL keyword not handled correctly

[ikirker]

Minimal example:

package main

import (
    "fmt"
    "github.com/xwb1989/sqlparser"
)

func main() {
    sql := "SELECT DATE_SUB(NOW(), INTERVAL 1 MONTH)"
    tree, err := sqlparser.Parse(sql)
    if err != nil {
        fmt.Println("Error: ", err)
        panic("oh no")
    }
    fmt.Println(tree)
}

$ go run main.go
Error:  syntax error at position 34 near 1
panic: oh no

[trace info]

Looks like it's failing to handle the MONTH after INTERVAL.
