Psycopg2 is a PostgreSQL database driver, it is used to perform operations on PostgreSQL using python, it is designed for multi-threaded applications. SQL queries are executed with psycopg2 with the help of the execute() method. It is used to Execute a database operation query or command.
psycopg2 2.9.5 Psycopg is the most popular PostgreSQL database adapter for the Python programming language. Its main features are the complete implementation of the Python DB API 2.0 specification and the thread safety (several threads can share the same connection).
psycopg2-binary and psycopg2 both give us the same code that we interact with. The difference between the two is in how that code is installed in our computer.

As intgr mentioned, if using with Django, Psycopg2 is recommended (Psycopg isn't supported anymore)
