We have another example to consider: pg_amcheck, which allows users to specify
multiple databases. Following this precedent, it may be beneficial to adopt a
similar style in pg_createsubscriber. E.g., Users could specify tables using
database-qualified names, such as:

./pg_createsubscriber --database db1 --table 'db1.public.t1' --table
'db1.public.t2(a,b) WHERE a > 100' --database db2 --table 'db2.public.t3'

This approach enables the tool to internally categorize specified tables by
database and create publications accordingly.
