This is a bit messed up. Either your Python environment is
inconsistent or it is WRT when psycopg was compiled. If you wanted to
investigate further maybe an "ldd /path/to/_psycopg.so" would suggest
you something.

What you may try to do is to create a virtualenv and pip install
psycopg2 into it, which would compile a fresh copy.
