Migrate Matrix Synapse from SQLite to PostgreSQL

Browse source 
SQLite over NFS caused database corruption (malformed disk image).
Recovered the DB, migrated data to PostgreSQL via synapse_port_db,
and updated the deployment to use psycopg2 with an init container.

Database: matrix on postgresql.dbaas.svc.cluster.local
Scaled replicas from 0 to 1.
