{"ram":"shared","disk_size":"1 GB","table_limit":"4,000","connection_limit":"20"} → {"ram":"shared","disk":"1 GB","connections":"20","table_limit":"4000"}

Heroku renamed fields in the Postgres Essential-0 limits (disk_size to disk, connection_limit to connections) and wrote the table limit as 4000 instead of 4,000. The values stayed the same: 1 GB disk, 20 connections, 4,000 tables.
