E.29.1. Migration to Version 9.3.1

A dump/restore is not required for those running 9.3.X.

However, if you use the hstore extension, see the first changelog entry.

Ensure new-in-9.3 JSON functionality is added to the hstore extension during an update (Andrew Dunstan)

Users who upgraded a pre-9.3 database containing hstore should execute
```
ALTER EXTENSION hstore UPDATE;
     
```
after installing 9.3.1, to add two new JSON functions and a cast. (If hstore is already up to date, this command does nothing.)
