How It Affects Your App
The error message PostgreSQL 57P03 CANNOT CONNECT NOW indicates that the application is unable to establish a connection to the PostgreSQL database. This means that the application will not be able to access any data stored in the database, and any operations that require data from the database will fail. This can have a significant impact on the application, as it will be unable to perform any of its intended functions.
How To Fix
