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 @name placeholders into positional $1 parameters, reuses parameter indices for repeated placeholders, and preserves PostgreSQL @@ operators without treating them as named placeholders
  2. pgx.NamedArgs allows unused arguments in the map and replaces missing query placeholders with nil values without error
  3. pgx.StrictNamedArgs returns an error when a query parameter is missing from the map or when unused keys are present in the map
  4. pgx.StructArgs converts struct and pointer fields with db tags (ignoring db:"-") into a query rewriter following NamedArgs semantics
  5. pgx.StrictStructArgs validates strict field matching and returns an error when struct fields are unreferenced in the query
