pg_waldump: command not found

Question

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

Answer 1

It is not in the default PATH, so you'll have to invoke it with its absolute path:

/usr/lib/postgresql/11/bin/pg_waldump <WAL file name>
