pg8000 is a pure-Python PostgreSQL driver that complies with DB-API 2.0. It is tested on Python versions 3.8+, on CPython and PyPy, and PostgreSQL versions 12+. pg8000's name comes from the belief that it is probably about the 8000th PostgreSQL interface for Python. pg8000 is ...

在postgresql数据库中fdw的支持,在创建和使用上都不上太方便,特别是fdw在用表级别关联的时候,性能会大大折扣,因为fdw的数据并不会落地到本地。所以我们可以利用postgresql对于python的支持,自行封装一个库对库的调度工具,将远端数据进行落地后再次使用。对于使用的便利性,读者可自行对比。
