Regarding https://forum.cockroachlabs.com/t/row-level-security-with-multi-tenancy/1294/2 - I can't find anything in the docs whether it's been implemented in later versions.
Ideally, if anyone can confirm this has been implemented, and where the docs are, that would be great.
Row-level security in available in CockroachDB starting with version 25.2. If you know the PostgreSQL implementation, the DDL syntax is nearly identical.
