Hi, There's a well known limitation in the amount of memory that any VACUUM process can use, capped at 1GB now. This is not reflected in the documentation
https://www.postgresql.org/docs/current/runtime-config-resource.html We should add a line that indicates that there is a limitation (that should be IMO, backported to documentation of earlier versions as it affects all supported versions), at least until such limitation is lifted. Kind regards, Martín -- Martín Marqués It’s not that I have something to hide, it’s that I have nothing I want you to see
