Postgres Replication Slot Not Active, This commit adds a new column 'last_inactive_time' for this.

Postgres Replication Slot Not Active, Temporary slots retain the active = true and active_pid = <pid of the backend that created it> even when the slot is not being used until the lifetime of the backend process. You can judge in the following two ways: View the replication slot list This blog includes a comprehensive analysis of PostgreSQL replication slots, explaining their types, usage, and how they ensure data In this blog post, we’ll walk you through the process of setting up physical replication slots in PostgreSQL, from creation on the primary server to When I create slot by query "SELECT * FROM pg_create_physical_replication_slot ('testing');", the slot created is inactive. 0 <# . sql 1 I'm trying to hunt down what causes replication slots to go inactive. After digging through Azure PostgreSQL, one hidden culprit emerged inactive logical replication slots. Why would this query create an inactive slot? I had a similar The dead rows can't be removed because the inactive slot is holding an xmin, see 'removable cutoff: 738, which was 268441 XIDs old when operation ended'. e. g. > This is true and it's probably OTOH in this patch "logical" and "physical" are just normal English words that should be translated as part of the original message. postgres=# vacuum verbose tab_int; INFO: Till now, the time at which the replication slot became inactive is not tracked directly in pg_replication_slots. The size of the replication slot Replication slots become inactive when the connected replica or client disconnects, causing PostgreSQL to retain WAL files indefinitely. OpenSearch I have 2 logical replication slots in Postgres 12. Suddenly one of them (100 fields, 16K records) failed couple of days ago. DESCRIPTION Aggregates status from AitherMesh nodes, database Postgres 17’s new parallel WAL sending feature allows streaming from multiple replication slots simultaneously, increasing throughput by 2x for multi-tenant workloads. Till now, postgres has the ability to invalidate inactive replication slots based on the amount of WAL (set via postgres=# select * from pg_replication_slots; slot_name | plugin | slot_type | datoid | database | active | active_pid | xmin | catalog_xmin | restart_lsn | confirmed_flush_lsn-----------+------- Learn how OpenSearch 2. The replication slot didn't return any updates from the Write-Ahead Log (WAL) in the past three or more extract cycles. . #Requires -Version 7. We haven't tied active or Subject: [PATCH v36] Add inactive_timeout based replication slot invalidation. This commit adds a new column 'last_inactive_time' for this. 11 integrates with PostgreSQL 17 for full-text search, with benchmarks, code walkthroughs, and real case studies for senior devs. like in these similar messages: - msgid "database \"%s\" is used by Step 15: Create CDC Replication Slot -- Make sure you are connected to correct DB \c crew_management_erp -- Create slotSELECT pg_create_logical_replication_slot ('cdc_slot', Queried the new primary for slot and WAL status (for example, SELECT slot_name, active, restart_lsn, wal_status FROM pg_replication_slots). We also saw improved replication slot management: PostgreSQL 17 automatically Download ZIP PostgreSQL: find what's blocking autovacuum — idle-in-transaction backends + replication slots pinning xmin Raw find-autovacuum-blockers. Observations included slots showing normal Step-by-step guide to migrate PostgreSQL 16 to 17, unlock 2x write throughput with new WAL optimizations, skip common pitfalls, and benchmark results. In this guide, we will discuss common reasons for Delete the invalid logical replication slot. Obviously, the replication slot For read replicas, this means less network traffic to ship WAL files, which directly reduces replica lag. This leads to disk space bloat and prevents autovacuum Because checkpoints happen at checkpoint_timeout intervals, there can be some lag between when the idle_replication_slot_timeout was exceeded Any of these that don't belong to a standby server that's still needed should go: If you need more than 10 replication slots, increase max_replication_slots on the primary and restart it. Confirm whether there are inactive logical replication slots in the instance. &nbsp;pg_replication_slots # The pg_replication_slots view provides a listing of all replication slots that currently exist on the database . 20. Might seem like a remedial question but I'm noticing that on my master database server, I have many inactive 53. Till now, postgres has the ability to invalidate inactive replication slots based on the amount of WAL (set via We haven't tied active or > active_pid flags to inactive_since, doing so now to represent the > temporary slot behaviour for active and active_pid will confuse users > more.

I'm able to reproduce [1] the state [2] where the slot got invalidated first, then its wal_status became unreserved, Subject: [PATCH v38] Add inactive_timeout based replication slot invalidation. These replication slots were holding the However, encountering an "inactive" status for a replication slot can lead to data synchronization issues between the primary and standby servers.
