This is a fork and restructuring of schickling's postgres-backup-s3 and postgres-restore-s3.

See backup/README.md and restore/README.md for further instructions.

Fork goals:

• dedicated repository
• automated builds
• support multiple PostgreSQL versions
• support encrypted (password-protected) backups
• merge backup and restore images?
