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 parameters into $1, $2 positional placeholders and extracts matching arguments in order
  2. assert pgx.NamedArgs reuses identical positional parameter placeholders when the same named argument appears multiple times in SQL
  3. assert pgx.NamedArgs preserves PostgreSQL full-text search operators @@ without interpreting them as parameter names
  4. assert pgx.NamedArgs binds missing named parameters as nil in the extracted arguments slice
  5. assert pgx.Identifier sanitizes schema and table names by wrapping in double quotes and escaping embedded quotes
  6. assert pgx.Identifier returns an empty string when given an empty identifier slice
  7. assert pgx.CopyFromSlice creates a CopyFromSource that iterates over rows and provides Values and Err state
