PostgreSQL 9.x Sequence Fixing Script

This script is intended to automatically fix the sequence numbers for all tables in the current database.

This is accomplished through the use of the setval() command, which we provide with the next ID value we wish to make use of. We use the setval(sequence, number, is_called) overload and set is_called = false in conjunction with COALESCE(MAX + 1, 1) to ensure that, with an empty table, the next sequence value is 1 as expected.

  // Drop a cookie on the recorder.
  http.SetCookie(recorder, &http.Cookie{Name: "test", Value: "expected"})
  
  // Copy the Cookie over to a new Request
  request := &http.Request{Header: http.Header{"Cookie": recorder.HeaderMap["Set-Cookie"]}}

Note

I would recommend @acdlite's redux-actions over the methods suggested in this Gist.

The methods below can break hot-reloading and don't support Promise-based actions.

Even though 'redux-actions' still uses constants, I've come to terms with the fact that constants can be good, especially in bigger projects. You can reduce boilerplate in different places, as described in the redux docs here: http://gaearon.github.io/redux/docs/recipes/ReducingBoilerplate.html
