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 parameters into 1-based positional placeholders ($1, $2, ...) and produces ordered argument values
  2. pgx.NamedArgs reuses positional placeholders when the same parameter name appears multiple times in SQL without duplicating arguments
  3. pgx.NamedArgs permits unused keys in map without returning an error
  4. pgx.NamedArgs supplies nil for parameters missing from the map without returning an error
  5. pgx.NamedArgs preserves original SQL and returns empty arguments slice when no named parameters are present
  6. pgx.NamedArgs preserves @ characters inside string literals and SQL comments without replacement
  7. sample helper functions RewriteNamedQuery, MergeNamedArgs, and BuildNamedQuery provide convenient query rewriting and map operations
