wal_recycle is new setting in PostgreSQL 12. By default it is ON. What will be the value for wal_recycle while using streaming replication in PostgreSQL 12 ?

  • [Quote from the manual](https://www.postgresql.org/docs/current/runtime-config-wal.html#GUC-WAL-RECYCLE) "*On COW file systems, it may be faster to create new ones, so the option is given to disable this behavior*" (COW = Copy On Write) –  Nov 23 '20 at 13:04
  • I'm still not clear what value we need to set if streaming replication is configured. – Darshan Shah Nov 24 '20 at 08:29

    This has nothing to do with streaming replication, rather with the filesystem you are using –  Nov 24 '20 at 08:31
  • ok. So in PostgreSQL 12 this is a new setting and will not affect the streaming replication. Default value for this setting is ON on my server. And will keep it as it is. Thanks. – Darshan Shah Nov 24 '20 at 08:35
