Question

My development database is SQLite but I deploy my app to Heroku and they are using PostgreSQL.

Now sometimes I have two different results coming out if I perform searches because PostgreSQL is case-sensitive but SQLite is not.

Shouldn’t Rails standardize these things? What methods should I use to solve that?

Here is how to fix it with raw SQL

Answer 1

Case insensitive searching in Postgres:

• use ilike instead of like (case-insensitive like)
• if you want to use =, make both sides either UPPER or LOWER
