    Example session with this skill installed

    Case: A service sees intermittent duplicate prepared statements after PgBouncer pool mode migration.

    Provided: client query errors and pool mode configuration (illustrative, partial). Potential exception: session statement cache retained across transaction reuse. Request an evidence-limited review, identify missing sources and required sign-off; do not perform a live system change.

    Repair PostgreSQL PgBouncer Prepared Statement Cache Drift — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    A service sees intermittent duplicate prepared statements after PgBouncer pool mode migration.

    Evidence register

    • S1: client query errors and pool mode configuration — PARTIAL / UNVERIFIED.
    • S2: authorized baseline or procedure — NOT PROVIDED; REQUIRED TO VERIFY.
    • S3: timestamped event and change context — NOT PROVIDED; REQUIRED TO VERIFY.
    • S4: responsible reviewer / approval record — NOT PROVIDED; REQUIRED TO VERIFY.

    Four checks

    1. Normalize identifiers and timestamps in client query errors and pool mode configuration; preserve original document revisions. — PENDING CORROBORATION.
    2. Locate session statement cache retained across transaction reuse and link every finding to exact source rows or event IDs. — PENDING CORROBORATION.
    3. Test whether the stated scenario is supported by the baseline, sequence constraints and independent counter-evidence. — PENDING CORROBORATION.
    4. Define an owner-reviewed, reversible verification sequence for reversible prepared-statement compatibility plan before any field or production change. — PENDING CORROBORATION.

    Deliverables

    • client query errors and pool mode configuration traceability crosswalk: DRAFT / INCOMPLETE until inputs are validated.
    • session statement cache retained across transaction reuse exception ledger: DRAFT / INCOMPLETE until inputs are validated.
    • reversible prepared-statement compatibility plan approval and validation plan: DRAFT / INCOMPLETE until inputs are validated.

    Decision gate

    INCOMPLETE — HUMAN REVIEW REQUIRED. Source chronology, approvals, scope and independent evidence have not been verified. No execution or live certification claimed.

    What to provide

    • client query errors and pool mode configuration
    • authorized baseline or procedure
    • timestamped event and change context
    • responsible reviewer / approval record

    Deliverables

    • client query errors and pool mode configuration traceability crosswalk.
    • session statement cache retained across transaction reuse exception ledger.
    • reversible prepared-statement compatibility plan approval and validation plan.

    Evidence policy The workflow uses only supplied, authorized evidence, separates source facts from inference and missing data, and does not claim live tests or certify external decisions. Owner approval is required for operational changes.

    Frequently Asked Questions

    This skill automates the identification of prepared statement conflicts (like 'S_1' errors) by cross-referencing your transaction logs with PgBouncer's pooling logic to find exactly where session-level data is leaking.

    It is compatible with any AI agent or LLM capable of processing structured text, provided you can upload or paste your PostgreSQL error logs and PgBouncer configuration files for analysis.

    The package includes the standardized analysis framework, a traceability crosswalk template for linking errors to specific events, and a step-by-step compatibility plan for your migration.

    No, this skill is a diagnostic and planning tool; it operates purely on the data you provide and does not require direct access or write permissions to your production databases.

    Yes, the framework is specifically optimized for 'pool_mode = transaction' scenarios where standard session-level statement caching typically breaks, helping you align application drivers with pooling constraints.

    Setup is minimal; you simply provide your client query errors, your current pool configuration, and a timestamp of when the issue started to begin the isolation process.
