31.7. Security
The role used for the replication connection must have
the
REPLICATION
attribute (or be a superuser). Access for the role must be
configured in
pg_hba.conf
and it must have the
LOGIN
attribute.
In order to be able to copy the initial table data, the role used for the
replication connection must have the
SELECT
privilege on
a published table (or be a superuser).
To create a publication, the user must have the
CREATE
privilege in the database.
To add tables to a publication, the user must have ownership rights on the table. To create a publication that publishes all tables automatically, the user must be a superuser.
To create a subscription, the user must be a superuser.
The subscription apply process will run in the local database with the privileges of a superuser.
Privileges are only checked once at the start of a replication connection. They are not re-checked as each change record is read from the publisher, nor are they re-checked for each change when applied.
