GCP Postgres

Prerequisites

• If your Postgres database is protected by security groups or other firewall settings, you will need to have the data-syncing service's static IP available to complete Step 1.

Step 1: Allow access

1. In your Google Cloud Console > SQL instances list, click the PostgreSQL instance you want to send data to.
2. In the instance page, click into the Connections tab on the left. Make a note of the Public IP address. Though not shown, you should use 5432 as the port.
3. In the Networking tab, ensure that the Instance IP assignment setting is set to Public IP to ensure that the destination is accessible from outside your VPC.
4. In the Authorized networks section, click Add a network. Enter a descriptive name (e.g., "data transfer service") and the data-syncing service's static IP and click Done.
5. Click Save.

Step 2: Create writer user

Create a database user to perform the writing of the source data.

1. Open a connection to your PostgreSQL database (locally or using the Google Cloud Shell).
2. Create a user for the data transfer by executing the following SQL command.

CREATE USER <username> PASSWORD '<some-password>';

3. Grant user create and temporary privileges on the database. create allows the service to create new schemas and temporary allows the service to create temporary tables.

GRANT CREATE, TEMPORARY ON DATABASE <database> TO <username>;

🚧

If the schema already exists

By default, the service creates a new schema based on the destination configuration (in the next step). If you prefer to create the schema yourself before connecting the destination, you must ensure that the writer user has the proper permissions on the schema, using GRANT ALL ON schema <schema> TO <username>;

Step 3: Add your destination

Securely share your host name, database name, port, your chosen schema name, username, and password with us to complete the connection.
