I think I've tried every combination of postgres 9.4 and 9.5 and psycopg2 and python. I've used Dependency Walker to examine dlls and read countless web pages. My current error is "ERROR: could not load library "C:/Program Files/PostgreSQL/9.4/lib/plpython3.dll": The specified procedure could not be found." Many people have encountered this error and there seems to be no shortage of "solutions". So my question is, does anybody have a clean set of instructions on how to get python working on a windows install of postgres; any version. I'm flexible, I can start fresh, I don't care which versions, I don't care if it's 32 bit or 64 bit. I just want to try it out.
