Just for the records, I asked here the same question and got some replies: https://dba.stackexchange.com/questions/186045/how-do-i-prevent-changes-to-my-database Am 11.09.2017 um 15:25 schrieb Thomas Güttler:
I did a stupid mistake. I run the final pg_dumpall without switching to single-user-mode first. With "final" I mean that the dump should be transferred to a different machine. After the dump the old machine was shut down forever. My mistake was that I stopped the services, but one process was still alive and this process inserted to the database after pg_dumpall has started. I guess I am not the first one who did this stupid mistake. What do you think? Wouldn't it be polite to add a note about this topic to the docs? Here are the docs for pg_dumpall: https://www.postgresql.org/docs/current/static/app-pg-dumpall.html How could the wording look like? I am not a native speaker .... Or do you have a better/different idea? Regards, Thomas Güttler
