Postgres Indexes for Newbies
The role of database indexes is similar to the index section at the back of a book. A database index stores information on where a data row is located in a table so the database doesn't have to scan the entire table for information. When the database has a query to retrieve, it goes to the index first and then uses that information to retrieve the requested data.
