To copy database from one heroku app to another -

heroku pg:backups capture [database_name]
heroku pg:backups restore $(heroku pg:backups public-url --app source_app) DATABASE_URL --app target_app

You can refer to https://devcenter.heroku.com/articles/heroku-postgres-backups for more information.

To copy database from local to heroku - Dump your local database in compressed format using the open source pg_dump tool: PGPASSWORD=mypassword pg_dump -Fc --no-acl --no-owner -h localhost -U myuser mydb > mydb.dump where myuser is your database username and mydb is the database name.

Setup: Intel Haswell, Debian. Both tests ran against the same image libraries (libjpeg-turbo etc).
Both ran on a single thread only. Save qualities were 85 for JPEG and WEBP, compress level 7 for PNG.
Both tests ran many iterations and then averaged results.
Benchmarking code can be found at https://github.com/discordapp/lilliput-bench

Test types:
- Header reading: We don't actually know what's in a blob of image bytes when we get it. Reading the header allows us
   to decide if we want to resize the image.
- Resize, 256x256 => 32x32: We have lots of icon-sized assets that we need resized into various smaller formats.
   These make up a pretty sizable percentage of our resizes.
