The Hyperledger Fabric SDK for Node.js provides a powerful API to interact with a Hyperledger Fabric blockchain. It provides default file-system wallet for storing fabric certificate and also provides a way to store certificates in Couch DB but not in Postgres. Explore this pattern further to understand how to use Postgres DB as Fabric wallet.

Hyperledger Fabric uses appropriate enrollment certificates while interacting with the blockchain network. The Hyperledger Fabric SDK for Node.js provides APIs to interact with a Hyperledger Fabric blockchain. Fabric Node SDK provides default file-system wallet for storing fabric certificate. File system wallet stores user certificate in folders. This approach does not provide required security, flexibility and also impacts scalability. Explore this pattern further to understand how to use PostgreSQL DB as Fabric wallet.
