How to restore database to previous state

Hi!

Postgres 12 database is runing on Debian

max_wal_size = 5GB

is specified in postgres.conf  file

How to restore database to some previous state, e.q. before important data was accidently deleted.

Binary asynchrunous replication with slot is also used.

I looks like it is possible to create standby server which replicates changes using 24 hour delay and data directory
backupsin 
 
every night.
However this requires separate delayed standby server .
Is there simpler solution, e.q reverse playback of wal segments starting from current data directory contents.

Andrus.
