According PostgreSQL documentation I can use pg_waldump for display a human-readable rendering of the write-ahead log of a PostgreSQL database cluster.
I have clean installation of PostgreSQL-11 server on Ubuntu 18.04, but I have not this command:
pg_waldump: command not found
Below list of present pg utilites:
pg_archivecleanup pg_conftool pg_dumpall pg_recvlogical pg_virtualenv pg_basebackup pg_createcluster pg_isready pg_renamecluster pg_buildext pg_ctlcluster pg_lsclusters pg_restore pg_config pg_dropcluster pg_receivewal pg_updatedicts pg_config.libpq-dev pg_dump pg_receivexlog pg_upgradecluster
What I need to do for use this command on my server
