It seems from a script that you are creating a subscription on the
same node as publication though in a different DB, right? If so, the
problem might be that copying the data of the first table creates a
transaction which blocks creation of the slot for second table copy.
The commit you referred will just fix the problem while reading the
data from the publisher not while writing data in the table in the
subscriber.

I guess you need to create a subscription on a different node.
