This file documents any backwards-incompatible changes in EHRBase deployment and assists users migrating to a new version.
The creation of the DB must ensure that SQL interval type is ISO-8601 compliant. This is required to ensure proper
formatting of the resultset.
Scripts provided ensure this encoding is done properly (see base/db-setup) with the following statement:
-- ensure INTERVAL is ISO8601 encoded
alter database ehrbase SET intervalstyle = 'iso_8601';
