PostgreSQL for Microsoft Windows Payload Execution

Description

On default Microsoft Windows installations of PostgreSQL the postgres service account may write to the current directory (which is usually "C:\Program Files\PostgreSQL\\data" where is the major.minor version of PostgreSQL). UDF DLL's may be sourced from there as well. This module uploads a Windows DLL file via the pg_largeobject method of binary injection and creates a UDF (user defined function) from that DLL. Because the payload is run from DllMain, it does not need to conform to specific Postgres API versions.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
