I am migrating a system from hsqldb to postgresql. I have a bunch of installs of this system live so moving the data is a headache. I was using identities in hsqldb and now I am using sequences. I was able to move all my data over however I am having an issue with the sequences. I default them all to start at a certain number; this works great for a fresh install. However when working with existing data the default is < the current number. ANd I have several installs and they are all different numbers. Is there a way to set it up so it knows to skip past existing ids? I would rather an automated solution but I was even trying something like this: ALTER SEQUENCE seq_address restart with (select max(id) from address) I guess that doesn't work because it wants a constant. Any suggestions? thanks
