SQS vs "Postgres Queue", I think mainly: - Closed/lock-in vs. Open/lock-free - Rigid data access pattern vs. Very flexible SQL access -Managed by AWS vs. Managed by you/your team (although you could use one of those managed Postgres services to reduce ops burden) - Integrates well with other AWS services (e.g. Lambda, SNS, DynamoDB, etc) vs. No integrations with AWS ecossystem out of the box
