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.ParseConfig parses PostgreSQL connection URI into ConnConfig
  2. pgx.ParseConfig extracts runtime parameters from query parameters
  3. pgx.ParseConfig parses key-value DSN format
  4. pgx.ParseConfig returns an error for invalid connection strings
  5. pgx.ConnConfig.Copy creates an independent copy of configuration
  6. pgx.NamedArgs rewrites named SQL parameters into positional placeholders
  7. pgx.StrictNamedArgs returns an error when a query parameter is missing
  8. pgx.Identifier sanitizes multi-part SQL identifiers and escapes embedded quotes
