Hint on how to restore

[cMurschall]

I'm really embarrassed to ask, but I inherited a project using your image and I wonder on how to restore a backup.
It's a totally noob question and I'm sorry, but I don't have much experience on how to service a postgres database and perhaps you have a hint for me.

I tried the accepted answer https://stackoverflow.com/a/29913462/4634044 but with no luck.

cat backup.sql | docker exec -i image psql --username=myusername

failes with
psql: FATAL: database "myusername" does not exist

Perhaps you could share how you restore your backups?

I figured out the problem: I was missing a -d databaseName parameter:

cat backup.sql | docker exec -i image psql --username=myusername --dbname=myDataBaseName

It would still be useful if there is a line added to the documentation describing how to do this.
