Thread: Why vacuum_freeze_table_age etc. doc in "Statement Behavior" section?
The explanations for vacuum_freeze_table_age etc. are in the section "Statement Behavior", which is a subsection of "Client Connection Defaults". To me vacuum_freeze_table_age etc. are totally unrelated to "Client Connection Defaults". I think "Resource Consumption" section is more appropriate for their place. There's already a section "Cost-based Vacuum Delay". Maybe we can add a new section for below under "Resource Consumption" something like "Managing Vacuum Freeze". vacuum_freeze_min_age vacuum_freeze_table_age vacuum_multixact_freeze_min_age vacuum_multixact_freeze_table_age Best regards, -- Tatsuo Ishii SRA OSS, Inc.

So +1 for a new section under Resource Consumption". -- Michael
