Use Range to make sure your reservations don't overlap in Postgres!
In apps involving start and end times, such as reservation or calendar apps, using range types in Postgres can bring many benefits, such as querying overlapping events or preventing overlaps under certain conditions.
Query ranges using the Supabase client library: https://supabase.com/docs/reference/j...
Range columns in Postgres represent the start and end of quantifiable data such as numbers, dates, or timestamps. Using ranges, you are introduced to advanced query operators along with exclude constraints that ensure no ranges overlap with each other under certain conditions, ensuring that reservations are protected at the database level.
