Enabling CDC (change data capture) for Postgres


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


Unfortunately, I can’t do it because doadmin is not a superuser.

Anyone had this issue before?

Hi there,

Because the doadmin user is not a superuser, you will not be able to create a publication for all tables.

But you can create a publication with the tables you want to replicate by explicitly specifying them, eg:

CREATE PUBLICATION datastream FOR TABLE table1, table2;

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.
