pg_waldump

pg_waldump is a tool to display a human-readable rendering of the Write-Ahead Log (WAL) of a PostgreSQL database cluster.

Warning

The WAL encryption feature is currently in beta and is not effective unless explicitly enabled. It is not yet production ready. Do not enable this feature in production environments.

To read encrypted WAL records, pg_waldump supports the following additional arguments:

  • keyring_path is the directory where the keyring configuration files for WAL are stored. The following files are included:
    • 1664_keys
    • 1664_providers

Note

pg_waldump does not decrypt WAL unless the keyring_path is set.
