Let's summarize.
To create a subscription into table X user must:
1. be a superuser
2. Or (have role pg_subscription_users
3. and be allowed to write into the table X)
4. Condition 3 can be replaced\extended by "be owner of a the table X".
5. Condition 2 can be replaced\extended by "have privileges for some server remote".
Which combination of authorization rules do we want?
IMHO 1,2,4 is sufficient.
