[Private Alpha] PostgreSQL Realtime opens to invited users
PostgreSQL Realtime is now available in Private Alpha. Browsers, Node.js, and WeChat Mini Program clients can now subscribe to database changes and states in real time using app.realtime() in the JavaScript SDK.
Realtime offers three core capabilities:
| Capability | Description |
|---|---|
| Broadcast | Low-latency custom messages within a channel |
| Presence | Track clients in a channel and their state |
| Postgres Changes | Push after INSERT, UPDATE or DELETE on a table |
Subscriptions to private channels are authorized by RLS policies on the realtime.messages table. On the management side, CLI v3.9.0 adds the tcb db pg realtime enable, get, and set commands.
