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 @param placeholders into positional $1, $2 placeholders in order of appearance
  2. pgx.NamedArgs reuses the same positional placeholder when a parameter appears multiple times in the query
  3. pgx.NamedArgs leaves escaped @@ literals intact in the rewritten query
  4. pgx.StrictNamedArgs fails when a required parameter in the query is missing from the arguments map
  5. pgx.StrictNamedArgs fails when an unused argument is supplied in the map
