Implicit casts, which have largely been removed from many areas of PostgreSQL, allow for PostgreSQL to cast data types when necessary to find functions or operators that are applicable. To actually get the data we want, we must use the double arrow operator (->>) to turn the terminal component of the path from "json" into a "text" type, followed by an explicit cast to the type we seek, like an integer. This tutorial will give you a quick start with PostgreSQL and make you comfortable with PostgreSQL.
