Support Postgress Adaptor "psycopg2" in python_pip workflow

**Description:**
Customers using Postgress with Lamnbda in Python run into the problem where this library does not load in AWS Lambda. This is a build time problem and not a runtime one. AWS Lambda does not include necessary `libpq.so` file required by Postgress in the runtime. So people have to compile & statically link this library.

Inizia individuando il workflow python_pip e analizzando come vengono compilate per AWS Lambda le dipendenze con librerie native. Confronta il comportamento attuale con il workaround collegato per psycopg2 su Lambda, quindi definisci e verifica un packaging riuscito per psycopg2; l’issue non indica file specifici né test da eseguire.
