THE GREAT MIGRATION FROM MONGODB TO POSTGRESQL

Infisical, a secrets management platform, migrated from MongoDB to PostgreSQL because of difficulties configuring transactions in MongoDB, a lack of relational features, inconsistent versioning across cloud providers, and a lack of a good user experience with MongoDB. The migration process required a temporary block on write operations and involved careful data transformation to map MongoDB's structure to PostgreSQL's relational model. LevelDB was used to persistently store and map identifiers between the databases. The migration itself led to significant performance gains and cost reductions.

DON’T USE YOUR ORM ENTITIES FOR EVERYTHING — EMBRACE THE SQL!

Object-Relational Mappers (ORMs) are useful tools, but shouldn't be treated as the only way to interact with your database. The belief that ORMs completely eliminate the need to write SQL is misguided - SQL should be used directly to optimize your database interactions. Using techniques like projections that select only the necessary data can improve performance a lot.
