Convert PostgreSQL to SQLite - Manuel van Rijn
Today Iâ€™d like to share the steps I take when I need to convert a PostgreSQL database into a SQLite database. Commonly I have to do this when a Ruby on Rails application is in production and I have to check some issues with the production data. In the production environment we usually use a PostgreSQL database and for developing I use a SQLite database, so we need some conversion. Short story a.k.
