You can replicate your database to other postgres servers. It is done by sending WALs. If you are not doing that, you don't need WAL senders. Replication can create a backlog of WAL files. Those files if what you're trying to get rid of. FWIW I left my few postgres-10 instances at the defaults, except for one that is actually replicated, they all seem to be honor the max_val_size, and the ones that are mostly idle have only 3-4 16MB files in pg_wal. So I don't know why yours is using too much space in pg_wal: it could grow over max_val_size when you run a lot of transactions, but then it should come down gradually. Checkpoint, specifically, should trigger that. -- Dmitri Maziuk <dmaz...@bmrb.wisc.edu> _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
