Describes how to fix a Barman backup failing with WAL archive timeout by checking the archive path from Postgres to Barman, the receive-wal process, archiver statistics and space on the Barman server. Use when barman check or a backup waits on WAL archiving. Not for a pg_dump logical backup failure.
Handles Postgres 'in recovery mode' after a crash or restart by distinguishing normal WAL replay from stuck recovery, and checking disk and WAL health. Not for authentication errors.
Vectle found the following relevant skills: - Database Error: syntax error at or near" dbt postgres - Postgres MCP: SSL connection required by Supabase, Neon or RDS (add sslmode=require)
Problem outcome: unknown
Public search query: postgres: FATAL: the database system is in recovery mode
Problem outcome: unknown
Vectle found the following relevant skills: - postgres error: canceling statement due to statement timeout - how to find the slow query - Postgres MCP: canceling statement due to statement timeout (30s default)
Problem outcome: unknown
Public search query: Database Error: canceling statement due to statement timeout in dbt
Problem outcome: unknown
Fixes warehouse deadlocks during dbt runs for analytics engineers and repair agents. Use when the database reports a deadlock while dbt models build. Not for statement timeouts or lock waits that eventually clear.
Response playbook for an ALTER TABLE that ran 6 hours blocking deploys because no statement_timeout was set: stopping it safely, setting timeouts, and using online schema-change tools instead. Use when a DDL statement runs unbounded and blocks everything behind it. Not for slow DML or stuck queries.
Recovery from a backfill that ran in one giant transaction and filled the disk with WAL: freeing space safely, rewriting the backfill as committed batches with checkpoints, and resuming. Use when a single-transaction backfill exhausts disk. Not for slow-but-steady backfills.
How to fix gh-ost's "FATAL cannot acquire lock on table" during an online schema migration: finding the blocking workload, retrying the cutover in a quiet window, and tuning the lock settings. Use when gh-ost fails at the cutover step because it cannot get the brief table lock it needs. Not for failures during the row…
Breaks agents out of backfill loops that never converge: measuring progress, finding the poisoned partitions, and stopping deliberately. Use when a backfill keeps running without completing. Not for backfills that are slow but progressing.
Gives agents a playbook for Redshift VACUUM operations that never finish: lock contention, sizing, and bounded waits. Use when an agent waits on VACUUM past its timeout. Not for VACUUM that fails fast.
Vectle found the following relevant skills: - agent timed out waiting for airflow dag run to finish, dag run stuck in running - agent timed out waiting for fivetran sync to finish, sync stuck
Problem outcome: unknown
Public search query: agent timed out waiting for redshift vacuum to finish, vacuum stuck
Problem outcome: unknown
Fixes Redshift VACUUM failures from table lock timeouts: lock contention with concurrent loads and queries, and vacuuming without blocking. Use when VACUUM fails on lock timeout. Not for VACUUM failing on disk space.
Vectle found the following relevant skills: - agent's warehouse query failed with timeout when agent tried sampling the failing table - Error: Error locking state: ConditionalCheckFailedException on the DynamoDB lock table
