Sequences : getting back the nextval() result on an insert

Hi

I am new to this list, but I've carefully searched the archives before posting this question.

I am using JDBC to access postgreSQL 6.3.

If one inserts records using a sequence to generate an auto-increment primary key, then you can get back the result by using "select currval('seq')". There is always a time between the insert and the select to retrieve the newly created primary key. What I do in my application is insert a record and display it in a java swing JTable (including the primary key).

How can I be certain that the primary key I retrieve with select currval('seq') is the one just inserted? Because in heavily loaded multi-user systems someone else can insert a record in the same table between my insert and my select.
