Hi Erik,

Does it end cleanly or with an error after 6 hours?

Do you have enough disk space for the vacuum full? The old and the newly
written data have to exist at the same time. Only after a successful
vacuuming the old data get deleted.

BTW, PG 9.2 has been out of service for quite some time. Only versions
11 to 15 are supported, with the support for version 11 lasting less
than a year.

Kind Regards,

Holger
