Looks like they're different technologies, found that oceandb has been offered in AliCloud under ApsaraDB umbrella https://www.alibabacloud.com/product/oceanbase

Fantastic! I was actually looking for a buggier version of postgres that won't be supported a year. That's exactly what I was looking for. > PolarDB will evolve and offer its functions and features in two major parts: Oh boy.
