 SchemaPlus::DefaultExpr augments the syntax for setting column defaults, to support expressions or constant values:

 If you are using Postgresql with a `json` column, ActiveRecord allows you to use a Hash for a default value.  Be aware that if the hash contains just one key which is `:expr` or `:value`, then SchemaPlus::DefaultExpr will interpret, and use the corresponding value for the default.  That is, these are equivalent:
 
-	t.json :fields, default: { value: { field1: 'a', field2: 'b' } }
