[pgpool-general: 69] unknown transaction isolation level:read uncommitted

[Mario Splivalo]

I have pgpool-II 3.1.1 set up on front of two postgres 9.1 boxes, in
streaming replication mode.

I have this error all over the pgpool logs:

pool_get_transaction_isolation: unknown transaction isolation level:read
uncommitted

Now, my application does set up transaction isolation to READ
UNCOMMITED, and postgres is setting it to READ COMMITED, but, why is
pgpool complaining about it?
