How to use pg_dump with a connection uri / url?

问题

I can invoke psql like this:

psql postgres://...

How can I use pg_dump with a connection string in the format postgres://...?
Would be more convenient than breaking URI's into host, post, username, password.

Is there syntax for this?

回答1:

Apparently it's as simple as this:

pg_dump postgres://username:password@ec2-00-00-100-100.eu-west-1.compute.amazonaws.com:5432/databasename

I just downloaded a dump using this format. Optionally you can add -f filename to specify a local filename.
