Hi. The documentation of ALTER SUBSCRIPTION REFRESH PUBLICATION [1] says:
---------- REFRESH PUBLICATION Fetch missing table information from publisher. This will start replication of tables that were added to the subscribed-to publications since the last invocation of REFRESH PUBLICATION or since CREATE SUBSCRIPTION. refresh_option specifies additional options for the refresh operation. The supported options are: copy_data (boolean) Specifies whether the existing data in the publications that are being subscribed to should be copied once the replication starts. The default is true. (Previously subscribed --tables are not copied.) ---------- But I found that default copy_data = true to be unintuitive. e.g. When I had previously done the CREATE SUBSCRIPTION using copy_data = false, then I assumed (wrongly) that the subscription default would remain as copy_data = false even when doing the REFRESH PUBLICATION. Is that a deliberate functionality, or is it a quirk / bug? ------ [1] https://www.postgresql.org/docs/devel/sql-altersubscription.html Kind Regards, Peter Smith. Fujitsu Australia
