Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. pgx.ParseConfig parses PostgreSQL connection URI and extracts parameters
  2. pgx.ParseConfig returns an error for invalid connection URI
  3. pgx.Identifier sanitizes multi-part SQL identifiers and escapes embedded quotes
  4. pgx.Batch queues SQL queries with arguments and tracks batch length
  5. pgx.CopyFromRows iterates through 2D slice rows sequentially and closes with nil Err
  6. pgx.CopyFromSlice maps index-based slice elements and iterates to completion
