Question
Enabling CDC (change data capture) for Postgres

Asked by Makara Sok
Hello,
I’m trying to replicate my database to Google Cloud BigQuery. It requires me to create a publication and a logical replication slot like this
> CREATE PUBLICATION datastream FOR ALL TABLES;
> SELECT PG_CREATE_LOGICAL_REPLICATION_SLOT('datastream_slot', 'PGOUTPUT');
Unfortunately, I can’t do it because doadmin is not a superuser.
Anyone had this issue before?

Hi @makarasok,
Are you using the DigitalOcean Managed Database product? In there you don’t have SuperUser rights as it’s a Managed Product.
I’ll recommend you to check the following docs of the product here:

It can help you with suggestions on the Migrate you are trying to do.
