pl/pgsql function result cache

I was thinking about pl/pgsql and comparing it with pl/sql function result cache, featured in Oracle 11g - see
http://www.oracle.com/technology/oramag/oracle/07-sep/o57plsql.html<br/><br />Is it possible to get pl/pgsql function
resultcache functionality into PostgreSQL real soon?<br /><br />Best,<br />Peter<br /><br /><hr />Discover the new
