How to set transaction isolation level for Postgres data source

Question

How to set global transaction isolation level for postgres data source.

I run jboss and I use hibernate to connect.

I know that I can set the isolation level from sleep mode, does this work for Postgres?

That would be by setting the hibernate hibernate.connection.isolation property to 1,2,4,8 - different values ​​of the corresponding static fields.

I am using org.postgresql.xa.PGXADataSource
