I encountered a problem in PostgreSQL 16:
In db1, there is a user table with fields id, name, phone, and createtime
db2 replicates the user table from db1 through logical replication, specifying
the fields as id, name, and createtime
Then, in db1, perform the following operation: alter table user
-privilege
replication slots, potentially leading to data security vulnerabilities.

absent from the replication slot?
If the replication slot does NOT include telphone data, this is a non-issue and
can be ignored.
3. I hope others in the community can address these suggestions, as I am not a
C developer and cannot implement them myself.

They
can subscribe to the replication slot and perform downstream processing
independently, without risking exposure of unauthorized data.
