Urgent please: PGPOOL II 2.3.3 hang in ssl mode

I am using Pgpool II 2.3.3 with Postgresql 8.3.8.

When I use command \l at postgresql client the query is working perfectly.

But if I used the command from pgpool II client which is connected with
postgresql in ssl mode, it gets hang.

Again if I use the command from pgpool II client in non-ssl mode, it works
fine.

Any help please.

When I use the following query it works :

SELECT d.datname as "Name",
r.rolname as "Owner",
d.encoding as "Encoding"
FROM pg_catalog.pg_database d
JOIN pg_catalog.pg_roles r ON d.datdba = r.oid
ORDER BY 1

But the following query does not work:

SELECT d.datname as "Name",
r.rolname as "Owner",
pg_catalog.pg_encoding_to_char(d.encoding) as "Encoding"
FROM pg_catalog.pg_database d
JOIN pg_catalog.pg_roles r ON d.datdba = r.oid
ORDER BY 1

The function call "pg_catalog.pg_encoding_to_char(d.encoding)" somehow makes
the Pgpool hang in SSL mode.

I found that the following works fine:

postgres=# create table mytab as select relname from pg_class limit 37;
SELECT
postgres=# select pg_relation_size('mytab');
pg_relation_size
------------------
8192
(1 row)

But, the folllowing hangs:

postgres=# select relname from pg_class limit 38;

Any help please. Its urgent.
