A few comments:
*
pg_createsubscriber.exe -D ..\..\data_standby -d db1 -d db2 -d db1
--publication pub1 --publication pub1 -P "dbname=postgres port=5432"
-p 5444 --dry-run
pg_createsubscriber: error: database "db1" specified more than once
for --database

Even when user has used short form, we are displaying long form for
database. I suggest to use both short and long form where applicable.

*
"invalid object type \"%s\" specified for --remove". Isn't it better
to use the short form as well in this error message?
