Include 3 previous tokens in syntax error message

    Hi!
    Postgres returns unreadable syntax error messageges like
    Syntax error at or near ')'
    If there are many ) characters in query, it is not possible to
      find the palce where error occurs. 

    
    STATEMENT_POSITION is difficult to use since drivers perform
      parameter replacements which makes this different from source
      position.
    How to fix this so that 3 last tokens are returned in message
      like
    Syntax error at or near ' i > )'
    Andrus.
