Thanks for the patch.

1)

+ The default is false. This option cannot be set together with
+ <literal>two_phase</literal> when creating the slot. However, once
+ the slot is created with <literal>two_phase=true</literal>, the
+ <literal>failover</literal> can be set to true after the
+ <literal>restart_lsn</literal> has advanced beyond its
+ <literal>two_phase_at</literal> value

As the user is not aware of two_phase_at, we shall change all the docs
to have a more user friendly explanation.

2)
# Confirm that the invalidated slot has been dropped.
$standby1->wait_for_log(
- qr/dropped replication slot "lsub1_slot" of database with OID
[0-9]+/, $log_offset);
+ qr/dropped replication slot "lsub1_slot" of database with OID [0-9]+/,
+ $log_offset);

I think this change is not needed.

thanks
