Nikolay and Michael discuss blue-green deployments — specifically an RDS blog post, how similar this is (or not) to what they understand to be blue-green deployments, and how applicable the methodology might be in the database world more generally.  Here are some links to things they mentioned: Fully managed Blue/Green Deployment in Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL https://aws.amazon.com/blogs/database/new-fully-managed-blue-green-deployment-in-amazon-aurora-postgresql-and-amazon-rds-for-postgresql/   Blue-green deployment (blog post by Martin Fowler) https://martinfowler.com/bliki/BlueGreenDeployment.html   Our episode on logical replication https://postgres.fm/episodes/logical-replication  pgroll https://github.com/xataio/pgroll  ~~~ What did you like or not like?
