A. Contact AWS Support to disable read-only mode on the read replica. Reboot the read replica. Connect to the read replica and create the tables.

Sorry C: - Do not think need to adjust anything like what is said in B: * We can edit default parameter group (no need of extra step of creating additional parameter group)
