Psycopg - Python PostgreSQL Database Adapter

  •        885

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). It was designed for heavily multi-threaded applications that create and destroy lots of cursors and make a large number of concurrent "INSERT"s or "UPDATE"s.

  •    Haskell

Hasql is a highly efficient PostgreSQL driver and a mapping API. It targets both the users, who need a low level of abstraction, and the users, who face the typical tasks of DB-powered applications, providing them with higher-level APIs. Hasql is not just a single library, it is a granular ecosystem of composable libraries, each isolated to perform its own task and stay simple.


epgsql - Erlang PostgreSQL client library.

  •    Erlang

Asynchronous fork of wg/epgsql originally here: mabrek/epgsql and subsequently forked in order to provide a common fork for community development.When you need to execute several queries, it involves a number network round-trips between the application and the database. The PostgreSQL frontend/backend protocol supports request pipelining. This means that you don't need to wait for the previous command to finish before sending the next command. This version of the driver makes full use of the protocol feature that allows faster execution.

go-sqlmock - Sql mock driver for golang to test database interactions

  •    Go

sqlmock is a mock library implementing sql/driver. Which has one and only purpose - to simulate any sql driver behavior in tests, without needing a real database connection. It helps to maintain correct TDD workflow.NOTE: in v1.2.0 sqlmock.Rows has changed to struct from interface, if you were using any type references to that interface, you will need to switch it to a pointer struct type. Also, sqlmock.Rows were used to implement driver.Rows interface, which was not required or useful for mocking and was removed. Hope it will not cause issues.
