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.NamedArgs rewrites named parameter placeholders into PostgreSQL positional parameters and orders arguments
  2. pgx.NamedArgs reuses identical positional parameter indices for repeated named parameters
  3. pgx.StrictNamedArgs returns an error when SQL query references an undefined parameter
  4. pgx.StrictNamedArgs successfully rewrites SQL query when all named parameters are present
  5. pgx.Identifier formats and sanitizes single and qualified multi-part SQL identifiers
  6. pgx.Identifier escapes embedded double quotes by doubling them
  7. pgx.TxOptions configures transaction isolation level, access mode, and deferrable mode
  8. pgx.QueryExecMode formats execution mode identifier as a non-empty string
