Verify Upgrade procedure for PostgreSQL 13 on Geo installations

We need to support upgrading GEO installations from PG12 to PG13. Initially this will be an opt-in upgrade.

The current procedure should not need to be deviated from significantly.

We should verify the following GEO installation types

  1. Single node primary and secondaries
  2. Separate database nodes on primary. Secondary with separate node running postgresql and geo-postgresql.
