    Repair Postgres Row Level Policy Session Pool Leak

    Example session with this skill installed

    Case: A reporting API occasionally sees an unrelated tenant row.

    Provided: PostgreSQL RLS policy definitions and pooled session transaction traces (illustrative, partial). Potential exception: tenant session variable survives connection reuse at pool release. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

    Repair Postgres Row Level Policy Session Pool Leak — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    A reporting API occasionally sees an unrelated tenant row.

    Evidence register

    • S1: PostgreSQL RLS policy definitions and pooled session transaction traces — 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 PostgreSQL RLS policy definitions and pooled session transaction traces; document missing or contradictory records. — PENDING CORROBORATION.
    2. Reconstruct the event sequence surrounding tenant session variable survives connection reuse at pool release, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
    3. Compare the evidence with the approved baseline; test the competing explanations for: A reporting API occasionally sees an unrelated tenant row. — PENDING CORROBORATION.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for session isolation negative tests and least privilege mitigation. — PENDING CORROBORATION.

    Deliverables

    • time-aligned evidence index for PostgreSQL RLS policy definitions and pooled session transaction traces: DRAFT / INCOMPLETE until inputs are validated.
    • exceptions and alternative hypotheses for tenant session variable survives connection reuse at pool release: DRAFT / INCOMPLETE until inputs are validated.
    • approval-gated session isolation negative tests and least privilege mitigation and verification criteria: DRAFT / INCOMPLETE until inputs are validated.

    About this skill

    Repair Postgres Row Level Policy Session Pool Leak is a ToolForge Labs Cursor Skill evidence-review workflow. Inspect tenant isolation after pooled session identity changes.

    What this skill checks

    1. Establish the identity, timestamp basis and revision lineage of PostgreSQL RLS policy definitions and pooled session transaction traces; document missing or contradictory records.
    2. Reconstruct the event sequence surrounding tenant session variable survives connection reuse at pool release, citing exact record identifiers and independent checks.
    3. Compare the evidence with the approved baseline; test the competing explanations for: A reporting API occasionally sees an unrelated tenant row.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for session isolation negative tests and least privilege mitigation.

    What to provide

    • PostgreSQL RLS policy definitions and pooled session transaction traces
    • approved operating baseline / documented policy
    • timestamped revision or change record
    • accountable reviewer and approval evidence

    Deliverables

    • time-aligned evidence index for PostgreSQL RLS policy definitions and pooled session transaction traces.
    • exceptions and alternative hypotheses for tenant session variable survives connection reuse at pool release.
    • approval-gated session isolation negative tests and least privilege mitigation 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.

    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.

    Frequently Asked Questions

    This skill specifically addresses 'session pollution,' where a user's identity persists in a pooled connection and allows a subsequent user to see their private data. It provides a structured framework to audit RLS policies and connection pooler configurations like PgBouncer to ensure tenant isolation remains intact.

    No, for security and safety, this skill is a non-executable analysis assistant. It analyzes your provided RLS definitions and logs to generate a mitigation plan and validation tests that you can review and run manually.

    This skill is designed for use with advanced LLM agents (such as ChatGPT, Claude, or custom LangChain agents) that support structured analysis and file uploads. It performs best when given access to your schema definitions and transaction log snippets.

    You receive the specialized investigation logic, a structured framework for trace reconstruction, and a set of templates for generating negative test cases. It is a one-time purchase that grants you the methodology to debug and audit RLS session leaks indefinitely.

    The skill works with any standard PostgreSQL environment (v9.5+) using Row Level Security, including managed services like Supabase, AWS RDS, or Azure Database. It is particularly effective for environments using session-level pooling rather than transaction-level pooling.
