It's not strictly necessary but it's very time series friendly (good compression, good indexing and partitioning etc). Nothing a pg expert can't accomplish with a vanilla postgres but very, very handy.
I haven’t tried timescale, but I have found postgres with time-based partitions works very well for timeseries data. Unless you’ve got really heavy indexes, the insert speed is phenomenal, like you said, and you’ve got the freedom to split your partitions up into whatever size buckets makes the most sense for your ingestion and query patterns.
A really nice pattern has been to use change data capture and kafka to ship data off to clickhouse for long-term storage and analytics, which allows us to simply drop old partitions in postgres after some time.
