extract and variables in PL/pgSQL - Mailing list pgsql-sql

Hi,

Someone in another list asked about this function. I'm not sure why it
doesn't work. What am I missing? 

CREATE FUNCTION zastras(timestamp) RETURNS integer AS '
declare w_temp1 alias for $1; w_result integer;
begin SELECT INTO w_result EXTRACT(epoch from timestamp w_temp1);  return w_result;

end;
' language 'plpgsql';

NOTICE:  Error occurred while executing PL/pgSQL function zastras
NOTICE:  line 5 at select into variables


Thanks,

-Roberto
