pg_dump and pg_restore are great, but they require more downtime. DTS is the way to go here.

DTS? Isn't that the tool that can also handle schema changes? Sounds like a winner to me.

I feel like pg_basebackup is more for full backups, so I doubt it would help with the migration process effectively.

pg_upgrade sounds familiar, but I can't recall if it actually minimizes downtime during migration.

I'm leaning towards D. pg_basebackup. It sounds like the most straightforward option to migrate the database with minimal disruption to the service. I'll make sure to read the details on how to use it properly.

Hmm, I'm a bit confused. I know pg_dump and pg_restore are common PostgreSQL backup/restore tools, but I'm not sure how they would work for migrating to Alibaba Cloud. I'll have to think this through carefully.

I'm not too familiar with Alibaba Cloud's database migration tools. I'd need to research D. DTS a bit more to see if that's the best choice for minimizing downtime.

I think D. pg_basebackup might be the best option here to minimize downtime. It can create a consistent backup of the database while it's still running.
