Repair WAL Archive Replay During Standby Promotion
Example session with this skill installed
Case: A read replica repeats rows while its logical slot retains old offsets.
Provided: PostgreSQL replication slots and LSN acknowledgement records (illustrative, partial). Potential exception: subscriber restart reuses stale confirmed flush LSN. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

Repair WAL Archive Replay During Standby Promotion — SYNTHETIC EVIDENCE-LIMITED REVIEW
Case received
A read replica repeats rows while its logical slot retains old offsets.
Evidence register
- S1: PostgreSQL replication slots and LSN acknowledgement records — PARTIAL / UNVERIFIED.
- S2: approved operating baseline / documented policy — NOT PROVIDED; REQUIRED TO VERIFY.
- S3: timestamped revision or change record — NOT PROVIDED; REQUIRED TO VERIFY.
- S4: accountable reviewer and approval evidence — NOT PROVIDED; REQUIRED TO VERIFY.
Investigation checks
- Establish the identity, timestamp basis and revision lineage of PostgreSQL replication slots and LSN acknowledgement records; document missing or contradictory records. — PENDING CORROBORATION.
- Reconstruct the event sequence surrounding subscriber restart reuses stale confirmed flush LSN, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
- Compare the evidence with the approved baseline; test the competing explanations for: A read replica repeats rows while its logical slot retains old offsets. — PENDING CORROBORATION.
- Draft a non-executing, owner-approved validation sequence and rejection criteria for logical decoding checkpoint and replay acceptance fixtures. — PENDING CORROBORATION.
Deliverables
- time-aligned evidence index for PostgreSQL replication slots and LSN acknowledgement records: DRAFT / INCOMPLETE until inputs are validated.
- exceptions and alternative hypotheses for subscriber restart reuses stale confirmed flush LSN: DRAFT / INCOMPLETE until inputs are validated.
- approval-gated logical decoding checkpoint and replay acceptance fixtures and verification criteria: DRAFT / INCOMPLETE until inputs are validated.
Decision gate
INCOMPLETE — HUMAN REVIEW REQUIRED. Sources, scope, time basis and sign-off remain unverified. No live change or approval has occurred.

Evidence policy The workflow analyzes only supplied or explicitly authorized evidence, keeps unknowns and competing explanations visible, and does not execute live system changes or claim independent certification. An authorized owner must approve operational decisions.
Find more skills like this on the Claude Skills Marketplace, the Codex Skills Marketplace and the Gemini Skills Marketplace, or browse Claude Skills for Data & Databases.
No live validation or direct platform access is asserted. Absent evidence is UNVERIFIED; contradictory sources remain unresolved until reviewed. Only authorized owners may approve real-world actions.
