Hi! Yes, I know I'm a horrible person to only now be updating a module to D6. Please forgive me. I am porting a module to Drupal 6 which used the `db_next_id()` function to get primary keys for a table. I would like to switch over to using autoincrement/db sequences (ie, schema type of 'serial') for this table. However, I need to provide an upgrade path. I've done a number of Google and Drupal.org searches, I've looked at taxonomy.install and system.install, and I can't seem to find any examples of where a column was upgraded from an old D5-style int-with- db_next_id-value to a serial. Are there any examples? I'd rather use a "best practices" method than a roll-my-own method. If there are none, I'm assuming the proper way to do it is to rename the tables, find the max of the old primary key, create the new tables, insert bogus rows until I hit the max value, delete currently unused values, copy over the current data, and then delete the old tables?
