コントラクト
- assert ConnectConfig panics when ConnConfig is manually initialized without ParseConfig
- assert ParseConfig extracts statement/description cache capacities and default_query_exec_mode into typed fields and strips them from RuntimeParams
- assert ParseConfig sets primary host in Host/Port and secondary hosts in Fallbacks (1 fallback for sslmode=disable, 3 for default prefer)
- assert pgx.ErrNoRows != sql.ErrNoRows by direct comparison but matches errors.Is(err, sql.ErrNoRows) and errors.Is(err, pgx.ErrNoRows)
- assert Row.Scan returns pgx.ErrNoRows on empty result set and rejects scanning into *pgtype.DriverBytes
