Manuel Kniep chce zrobić o tym prezentacjęcreate custom datatypes with postgres for rails 4
I want to show how you can create custom datatypes in postgres and add automatic type casting for them with rails 4.
This will be shown by extending the postgres hstore datatype for the special need of having integers as values. The talk will also cover creating functions, operators, and aggregators in postgres.
So it will be 80% postgres and 20% rails.
