JQuery :: Pagination Direct From The Database Without A Large Default List To Paginate

I need a plugin or a idea about how to develop a pagination using jQuery (JSON dict coming from the DB (postgre)), but i cant get a list of all itens in the DB. I tried using offset and limit from the DB, but i didnt like the large algorithm. All i need is: develop a pagination that gives me only 20 rows from the DB (without calling a query to paginate all table from DB) and build a pagination with "first page, previous page, X-2, X-1, X, X+1, X+2, next page, last page" (X = number of actual page).
