I'm in the same camp. Do you use any specific extensions? Especially for OLAP and time series (partitioned tables + related extensions work fine, but curious if you use anything else)
The native extensions are fine but I don't have good experience with any third party extensions, so far tried Timescale, pg_lake, citus, and pgvectorscale. They look very appealing but it's usually a trap as you can't get the value without using the vendor's cloud offerings.
I think if you grow enough to look for these extensions, it's usually better to bet on purpose-specific tooling. For example, I use DuckDB/Iceberg combination extensively for columnar data and connect DuckDB to PG when I need it.
From experience, I'd suggest using ClickHouse beyond a few billion rows of timeseries data in Postgres.
