This is strictly a breaking change for TimescaleDB users (nothing else has changed). Previously OhmGraphite would create a schema and initialize the Timescale table. While convenient, creating tables, indices, etc automatically is not desirable for an application that could be installed on many client machines. In production, one may want to create indices on other columns, omit an index on the host column, or create custom constraints. OhmGraphite shouldn't dictate everything. In fact, OhmGraphite should be able to function with a minimal amount of permissions. That is why with the 0.7 release, automatic creation of tables, etc is opt-in via the new timescale_setup option.
Recommendation: create a user that can only insert into the ohm_stats table
CREATE USER ohm WITH PASSWORD 'xxx';
GRANT INSERT ON ohm_stats TO ohm;Then initialize the ohm_stats appropriately.
If one desires OhmGraphite to automatically setup the table structure then update the configuration to include timescale_setup
<add key="timescale_setup" value="true" />A side benefit of this update is that OhmGraphite can now insert into traditional PostgreSQL databases.
