Hi,
I had a few comments for the 0003 patch.
1).
- This clause alters parameters originally set by
- <xref linkend="sql-createsubscription"/>. See there for more
- information. The parameters that can be altered
- are <literal>slot_name</literal>,
- <literal>synchronous_commit</literal>,
- <literal>binary</literal>, and
- <literal>streaming</literal>.
+ This clause sets or resets a subscription option. The parameters that
can be
+ set are the parameters originally set by <xref
linkend="sql-createsubscription"/>:
+ <literal>slot_name</literal>, <literal>synchronous_commit</literal>,
+ <literal>binary</literal>, <literal>streaming</literal>.
+ </para>
+ <para>
+ The parameters that can be reset are: <literal>streaming</literal>,
+ <literal>binary</literal>, <literal>synchronous_commit</literal>.
Maybe the doc looks better like the following ?

2).
- opts->create_slot = defGetBoolean(defel);
+ if (!is_reset)
+ opts->create_slot = defGetBoolean(defel);
}
Since we only support RESET streaming/binary/synchronous_commit, it
might be unnecessary to add the check 'if (!is_reset)' for other
option.
3).
typedef struct AlterSubscriptionStmt
{
NodeTag type;
AlterSubscriptionType kind; /* ALTER_SUBSCRIPTION_OPTIONS, etc */
Since the patch change the remove the enum value
'ALTER_SUBSCRIPTION_OPTIONS', it'd better to change the comment here
as well.
