Question

I launched a webapp that uses JPA/Hibernate with a Postgres DB. I want to increase the lower bound for generated keys, so the site doesn’t look so “new.”

How can I do this with hibernate and/or postgres? I know in MySQL you can set the starting value for AUTO_INCREMENT, and I’m looking for a similar feature. Any solution is fine, whether its a hibernate config ( I’m using annotations ) or a one time thing I can diddle in the DB to make future keys start higher.

Thanks!

I assume you are using sequences in postgresql.

You have to go through every of them and set the next value to be higher:

ALTER SEQUENCE serial RESTART WITH 105;

105 is the new id.
