-    ### Variants:
-    - `On`: The meaning may change based on whether you have
-        a synchronous standby or not.
-        If there is a synchronous standby,
-        setting the value to on will result in waiting till “remote flush”.
-    - `Off`: As the name indicates, the commit acknowledgment can come before
-        flushing the records to disk.
-        This is generally called as an asynchronous commit.
-        If the PostgreSQL instance crashes,
-        the last few asynchronous commits might be lost.
-    - `Local`: WAL records are written and flushed to local disks.
-        In this case, the commit will be acknowledged after the
-        local WAL Write and WAL flush completes.
-    - `RemoteWrite`: WAL records are successfully handed over to
-        remote instances which acknowledged back
-        about the write (not flush).
-    - `RemoteApply`: This will result in commits waiting until replies from the
-        current synchronous standby(s) indicate they have received
-        the commit record of the transaction and applied it so
-        that it has become visible to queries on the standby(s).
