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.BeginFunc initiates transaction on db, calls callback function, and commits upon successful return
  2. pgx.BeginFunc rolls back transaction and propagates error when callback function returns error
  3. pgx.BeginFunc returns db.Begin error immediately without invoking callback when transaction start fails
  4. pgx.BeginFunc returns commit error when callback succeeds but transaction commit fails
  5. pgx.BeginTxFunc passes configured TxOptions to db.BeginTx and commits transaction upon callback completion
  6. pgx.BeginTxFunc rolls back transaction and propagates error when callback fails with TxOptions configured
  7. sample helpers WithTransaction, WithTransactionOptions, WithReadonlyTransaction, and WithSerializableTransaction provide convenient transactional execution wrappers
