Importing data from Amazon S3 into an RDS for PostgreSQL DB instance

You can import data that's been stored using Amazon Simple Storage Service into a table on an RDS for PostgreSQL DB instance. To do this, you first install the RDS for PostgreSQL aws_s3 extension. This extension provides the functions that you use to import data from an Amazon S3 bucket. A bucket is an Amazon S3 container for objects and files. The data can be in a comma-separate value (CSV) file, a text file, or a compressed (gzip) file. Following, you can learn how to install the extension and how to import data from Amazon S3 into a table.

Your database must be running PostgreSQL version 10.7 or higher to import from Amazon S3 into RDS for PostgreSQL.

If you don't have data stored on Amazon S3, you need to first create a bucket and store the data. For more information, see the following topics in the Amazon Simple Storage Service User Guide.

Cross-account import from Amazon S3 is supported. For more information, see Granting cross-account permissions in the Amazon Simple Storage Service User Guide.

You can use the customer managed key for encryption while importing data from S3. For more information, see KMS keys stored in AWS KMS in the Amazon Simple Storage Service User Guide.
