Provided you're just performing a simple pg_upgrade without making schema changes or any wholesale database changes, then, even if the upgrade is a major version change, you really shouldn't have any issues. At least I've never had any problems with this.

Thanks for fast responce.Could this iteraction roles, schemas, databases - e.g. configurations in pg_hba.conf - between multiple databases and different Postgres minor version e.g. 9.6 to 9.6.1 cause trouble when upgrading still between minor versions?An if any potential problems would this be announced in release comments.Thanks.2017-03-10 16:17 GMT+01:00 John Scalia <jayknowsunix@xxxxxxxxx>:JayYes, (or is that too glib?)Roles are global in postgresql, so it's just a simple grant assignment.
