InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
I should also add that there is a duckdb fdw, so you could have DuckDB read from your parquet files and do faster transformations before you pull your data into Postgres!
