read uncomitted data in postgres

HI
I am converting an application from Sql Server to Postgres and would like to know if there is any way to get uncommitted data.
Postgres claims to accept the READ UNCOMMITTED isolation level but actually maps it to READ COMMITTED

Open in new window

We have a bunch of long transaction and a GUI that reads the data updated in the time life of the transaction and update visual statuses, it does this using the READ UNCOMMITTED isolation level.
any advice how to perform those transactions and still display the "dirty" data.

Thanks

Sorry but there is just no way to do that in PostgreSQL at the moment and I'm not aware of any future plans to add it, despite having the option in the set transaction statement.
