ASK HN: Facing problems in PostgreSQL Database Backup, help?

I've been using the PGDump utility however I often find the following problems -

  -  fails for larger databases,
  -  takes a long time to process,
  -  restoration doesn't always work,
  -  backup/restore doesn't work for a few selected tables

Thus, I've been looking for ideal solutions for the same. One that handles these edge cases. I've also thought about building a tool myself for the same.

If you have a solution, please help -- if you would like to play with a better solution - please leave your info here: https://airtable.com/shrmAi6hbImX2LGo4

Thanks a ton, folks!
