Add support for TimescaleDB

[ei8ht187]

Minigcore is already using PGSQL for persistence. As far as I can tell a lot of this persistent data are time series. Therefore support for TimescaleDB https://www.timescale.com/ and its features should be considered.
TimescaleDB is an enhancement to PQSQL, specially for time series data.
