 * Start server

+#### Upgrading from 2.3.* to 2.4.*:
+
+* Stop your server
+* Update ptrack binaries
+* Start server
+* Do `ALTER EXTENSION 'ptrack' UPDATE;`.

 ## Limitations
 
 1. You can only use `ptrack` safely with `wal_level >= 'replica'`. Otherwise, you can lose tracking of some changes if crash-recovery occurs, since [certain commands are designed not to write WAL at all if wal_level is minimal](https://www.postgresql.org/docs/12/populate.html#POPULATE-PITR), but we only durably flush `ptrack` map at checkpoint time.
