G2Snapshot cannot find psycopg2 even though it is installed

[jbutcher21]

This means we cannot take a snapshot against a postgres database. Actually G2Snapshot recognizes it can't get to the database and does an api export instead.

To replicate the problem just go into python3 in the container and try to "import psycopg2". It will error and say it cannot be found. Yet the Dockerfile does install it.

After clever debugging from Ant, adding this to the PYTHONPATH fixes it:

export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3.9/dist-packages:/usr/lib/python3/dist-packages:/usr/lib/python3/dist-packages/IPython/extensions

He suggested that changing the setting of PYTHONPATH in the Dockerfile is overwriting instead of updating. Maybe export PYTHONPATH=$PYTHONPATH:/opt/senzing ... etc will fix it.
