This is almost certainly a problem with your persistence layer rather than with Postgres. If you can see the data with PGAdmin then it's in the database. It may be that the transaction that saves the object is not committing quickly, and so other connections don't see the object until the commit happens. But that's not the fault of Postgres. -Doug
