Re: Enhance 'pg_createsubscriber' to retrieve databases automatically when no database is provided.

Hi Shubham,

Here are a few comments for the v12 patch.

doc/src/sgml/ref/pg_createsubscriber.sgml :

1.
+      <para>
+       For all source server non-template databases create subscriptions for
+       create subscriptions for databases with the same names on the
+       target server.

is “create subscriptions for” repeated? The sentence doesn’t make sense.

2. Typo
+       switches. This option cannot be together with <option>--all</option>.

/cannot be together/cannot be used together/
~~~

3. src/bin/pg_basebackup/pg_createsubscriber.c :
+ /* Establish a connection to the PostgreSQL server */
+ conn = connect_database(opt->pub_conninfo_str, true);

I think comment will be more clear if say “ Establish a connection to
the primary server */ or “source server”
~~~

src/bin/pg_basebackup/t/042_all_option.pl :

4. As per Ashutosh's comment at [1], tests need to be added to verify
logical replication behavior after using the --all option.

Please refer to the attached top-up fix patch, which includes the
above changes along with some cosmetic fixes in the test file
042_all_option.pl.
