如何从heroku上托管的PostgreSQL数据库下载Schema？

Question

I would like to create a ERM-Diagram from a PostgreSQL Database which is hosted on heroku. The database itself is almost 20 GB big, which makes downloading the whole dump not an option.

Is there a way to simply backup and download the schema including foreign keys, and maybe 10 rows of each table in the database, which could subsequently be restored into a local dabase via the psql -command?

I have the PG Backups Plus addon enabled, but that seems to only enable me to dump the whole database with the complete dataset.

Use pg_dump instead. The --schema-only|-s option does just what you're looking for.

pg_dump --schema-only -h host -U user -f schema_dump_file dbname

Then just manually grab a bit of data that you want. There's no easy way, that I know of or seen, around that.
