Execution from java - slow

Hello all,

I have a plpgsql function that takes a few seconds (less than 5) when
executed from psql. The same function, when invoked from java via a
prepared statement takes a few minutes. There are a few queries in the
function. Out of these, the first query takes input parameters for
filtering the data. It is this query which takes a long time when the
procedure is invoked from java. To ensure that the query does use actual
values (and not bind variables) for optimization, we used

execute
'
select x.col_type_desc,x.acc_id,acc_svr from (.....
'
using d_from_date,d_to_date

It did not help. Any suggestions? It is from_date and to_date on which
data gets filtered. We are using the same values for filtering, when we
execute it from java/psql

Regards,
Jayadevan
