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 valid PostgreSQL connection URI into ConnConfig
  2. pgx.ParseConfig populates host, port, database, user, password, and runtime params
  3. pgx.ParseConfig parses key-value style connection string
  4. pgx.ParseConfig returns an error for invalid connection strings
  5. pgx.NamedArgs defines key-value query arguments
  6. pgx.Identifier sanitizes and quotes SQL identifiers correctly
  7. pgx.Batch queues SQL queries for execution
  8. pgx.CopyFromRows creates a copy source from row slices
