set_literalizer.rb

The set_literalizer extension allows for using Set instances in many of the same places that you would use Array instances:

DB[:table].where(column: Set.new([1, 2, 3]))
# SELECT FROM table WHERE (column IN (1, 2, 3))

To load the extension into all datasets created from a given Database:

DB.extension :set_literalizer
