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.QueryRewriter defines RewriteQuery interface to rewrite SQL queries and arguments before database execution
  2. pgx.NamedArgs implements pgx.QueryRewriter by transforming named parameters to positional placeholders and arguments
  3. pgx.StrictNamedArgs implements pgx.QueryRewriter with strict parameter presence validation and error propagation
  4. custom QueryRewriter implementations can prepend metadata comments and modify SQL strings
  5. custom QueryRewriter implementations can enforce query safety and reject unsafe queries with custom errors
  6. sample helpers ChainedRewriter and ExecuteRewriters compose multiple QueryRewriters sequentially and propagate errors
