Which Items Occupy the Storage Space of My RDS for PostgreSQL Instances?

Both your regular data (backup data not included) and the data required for the operation of your DB instances (such as system database data, WAL logs, and indexes) take up storage space on your DB instances. The storage space includes the file system overhead required for inode, reserved blocks, and database operations. Log files generated by RDS for PostgreSQL database servers also occupy storage space.

These files ensure the stability of RDS for PostgreSQL instances.
