    Repair Postgres Logical Slot Feedback LSN Gap

    Example session with this skill installed

    Case: Logical consumer resumes from an earlier LSN after connection recycling.

    Provided: Postgres replication slot confirmed flush positions and consumer feedback logs (illustrative, partial). Potential exception: acknowledged write position advances before durable consumer offset persistence. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

    Repair Postgres Logical Slot Feedback LSN Gap — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    Logical consumer resumes from an earlier LSN after connection recycling.

    Evidence register

    • S1: Postgres replication slot confirmed flush positions and consumer feedback logs — 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

    1. Establish the identity, timestamp basis and revision lineage of Postgres replication slot confirmed flush positions and consumer feedback logs; document missing or contradictory records. — PENDING CORROBORATION.
    2. Reconstruct the event sequence surrounding acknowledged write position advances before durable consumer offset persistence, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
    3. Compare the evidence with the approved baseline; test the competing explanations for: Logical consumer resumes from an earlier LSN after connection recycling. — PENDING CORROBORATION.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for database owner feedback ordering fixture and data gap containment review. — PENDING CORROBORATION.

    Deliverables

    • time-aligned evidence index for Postgres replication slot confirmed flush positions and consumer feedback logs: DRAFT / INCOMPLETE until inputs are validated.
    • exceptions and alternative hypotheses for acknowledged write position advances before durable consumer offset persistence: DRAFT / INCOMPLETE until inputs are validated.
    • approval-gated database owner feedback ordering fixture and data gap containment review and verification criteria: DRAFT / INCOMPLETE until inputs are validated.

    What to provide

    • Postgres replication slot confirmed flush positions and consumer feedback logs
    • approved operating baseline / documented policy
    • timestamped revision or change record
    • accountable reviewer and approval evidence

    Deliverables

    • time-aligned evidence index for Postgres replication slot confirmed flush positions and consumer feedback logs.
    • exceptions and alternative hypotheses for acknowledged write position advances before durable consumer offset persistence.
    • approval-gated database owner feedback ordering fixture and data gap containment review and verification criteria.

    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.

    Frequently Asked Questions

    This skill specifically addresses scenarios where a consumer resumes from a stale LSN after a disconnect, causing WAL bloat or replication lag. It uses a structured evidence-based framework to distinguish between confirmed flush positions and actual consumer durability, preventing unnecessary data re-syncs.

    The skill is compatible with any AI agent that supports structured diagnostic workflows and file-based log analysis. It is designed to work with standard PostgreSQL 10+ logical replication logs and telemetry from `pg_replication_slots`.

    You will receive the complete diagnostic framework, including the Evidence Indexing protocol, Event Reconstruction logic, and standardized templates for Gap Validation and owner approval.

    No, this skill is a diagnostic and advisory tool; it analyzes logs and telemetry to provide a verified sequence of events and a repair plan. The final execution of LSN advances or consumer resets remains under the manual control of the database administrator for safety.

    You should provide time-series logs from your replication consumer (e.g., Debezium, pg_recvlogical) and snapshots of the `pg_replication_slots` view showing `confirmed_flush_lsn` and `restart_lsn` values.

    Buyers receive lifetime access to the current version of the skill; significant updates to the underlying diagnostic logic or support for new Postgres major versions are typically provided as free updates to existing license holders.
