Thanks!

Some comments.

Looking at 0002:

1 ===

+      <para>The following options are supported:</para>

What about "The following option is supported"? (as currently only the 
"FAILOVER"
is)

2 ===

What about adding some TAP tests too? (I can see that ALTER_REPLICATION_SLOT 
test
is added in v68-0004 but I think having some in 0002 would make sense too).

Looking at 0003:

1 ===

+      parameter specified in the subscription. When creating the slot,
+      ensure the slot <literal>failover</literal> property matches the
+      <link 
linkend="sql-createsubscription-params-with-failover"><literal>failover</literal></link>
+      parameter value of the subscription.

What about explaining what would be the consequence of not doing so?
