<para>
This parameter is intended for use with streaming replication deployments;
however, if the parameter is specified it will be honored in all cases.
Synchronous replication is not affected by this setting because there is
not yet any setting to request synchronous apply of transaction commits.
<varname>hot_standby_feedback</> will be delayed by use of this feature
which could lead to bloat on the master; use both together with care.
<warning>
<para>
Synchronous replication is affected by this setting when <varname>synchronous_commit</varname>
is set to <literal>remote_apply</literal>; every <literal>COMMIT</literal>
will need to wait to be applied.
