I decided to tee my timeseries data into InfluxDB.  Purpose built for the task and has builtin support for rollups&#x2F; aggregation&#x2F; retention policy&#x2F; gap filling.  Admittedly I have not put Influx under much stress or scalability testing since my use case is more based on utility than performance.<p>Unless PG has some timeseries-specific extensions I have assumed it would be appropriate for a TS-specific database.  Also curious to try Riak TS.
