Feature Type

• Adding new functionality to pandapower

• Changing existing functionality in pandapower

• Removing existing functionality in pandapower

Problem Description

There are several reasons, why somebody exposes Postgresql on a port other then 5432.

From my understanding of the docs, it is currently not possible to explicitly specify the port of the Postgresql server.

It might also be worth considering to pass an already existing connection to the function.

Feature Description

Version 3.1.2
in panadpower/sql_io.py, line 20
The function signature has no parameter for the port.

Additional Context

No response
