As the documentation says at: https://www.postgresql.org/docs/current/static/runtime-config-resource.html#GUC-OLD-SNAPSHOT-THRESHOLD | Useful values for production work probably range from a small | number of hours to a few days. The setting will be coerced to a | granularity of minutes, and small numbers (such as 0 or 1min) are | only allowed because they may sometimes be useful for testing. -- Kevin Grittner EDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
