pg_waldump

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

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

  • keyring_path: the directory where keyring configuration files for WAL are stored. These files include:
  • pg_tde.map
  • pg_tde.dat
  • pg_tde_keyrings

Note

pg_waldump will not decrypt WAL unless the keyring_path is set.
