psycopg2 is a Python _module_ so you'll never end up linking it
statically with your application. The requirements of the LGPL3 are
_already_ taken care of by simply distributing psycopg2 as a module
together with your application. If you don't change psycopg2 code you
don't have any other burden and nothing in the LGPL3 says you should
expose your code in this case.

 When people say things are a lot more complicated than that, they
  means they're getting worried that they won't like the truth.
