The command

./develop.sh manage init_ts_db -f

throws an error 

sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) FATAL: password authentication failed for user "timescale_lb"

This might be due to the reason that on running the above command it runs the queries in admin.timescale.drop_db.sql which also drops the timescale_lb user. The timescale_lb  user gets created during execution of the following code and queries but no password is associated with it.

This can be tackled by running the queries in admin.timescale.create_db.sql which creates the user, associates password with it and fixes the __ error.
