I was able to solve my issue based on instructions from this question. Basically, postgres privileges needed to be re-granted to the db user. In my case, that was the user I had setup in the virtual environment settings file. Run the following from the commandline (or within postgres) where mydatabase and dbuser should be your own database and user names:
psql mydatabase -c "GRANT ALL ON ALL TABLES IN SCHEMA public to dbuser;"
psql mydatabase -c "GRANT ALL ON ALL SEQUENCES IN SCHEMA public to dbuser;"
psql mydatabase -c "GRANT ALL ON ALL FUNCTIONS IN SCHEMA public to dbuser;"
