Add a new JSON column

ID: E3

A new column of type json was added to a table. This breaks SELECT DISTINCT queries or other operations that need equality checks on the column. A safer way is: Use the jsonb type instead, it supports all use-cases of json and is more robust and compact.

Created column meta with type json. The json type does not support equality and should not be used, use jsonb instead.
