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. assert pgx.NamedArgs rewrites named parameter placeholders into positional placeholders and extracts values in order of appearance
  2. assert pgx.NamedArgs reuses identical positional parameter index for repeated named parameters and dedupes extracted arguments
  3. assert pgx.NamedArgs distinguishes PostgreSQL @@ text search operators and preserves them without parameter replacement
  4. assert pgx.NamedArgs ignores @ characters contained within quoted string literals
  5. assert pgx.NamedArgs maps missing map keys to nil parameter values bound to corresponding positional placeholders
  6. assert pgx.NamedArgs ignores unused map keys without error
  7. assert pgx.StrictNamedArgs returns an error when map contains unused parameter keys
  8. assert pgx.NamedArgs returns unchanged SQL and empty args slice for queries without named parameters
