Specifies whether to drop the replication slot on the publisher. The

default is

|
<literal>DROP SLOT</literal>.

<para>
|

If the publisher is not reachable when the subscription is to be
|
||
|
|
dropped, then it is useful to specify <literal>NODROP SLOT</literal>.
|
||
|
|
But the replication slot on the publisher will then have to be removed
|
||
|
|
manually.
