* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.

* [PATCH 1/2] REPACK: do not require the user to have REPLICATION @ 2026-04-20 09:38 Álvaro Herrera <[email protected]> 0 siblings, 0 replies; 261+ messages in thread From: Álvaro Herrera @ 2026-04-20 09:38 UTC (permalink / raw) Although REPACK (CONCURRENTLY) uses replication slots, there is no concern that the slot will leak data of other users, because the MAINTAIN privilege on the table is required anyway; requiring REPLICATION is user-unfriendly without providing any actual protection. A related aspect is that the REPLICATION attribute is not needed to prevent REPACK from stealing slots from logical replication, since commit e76d8c749c31 made REPACK use a separate pool of replication slots. Because there are now successful concurrent repack runs in the regression tests, we're forced to run test_plan_advice under wal_level=replica.
