Question

I’ve recently gone through the database migration process as outlined here:

https://devcenter.heroku.com/articles/migrating-from-shared-database-to-heroku-postgres

Now I’m seeing a number of errors in the logs like this:

PGError: ERROR: permission denied for relation

Any ideas on what I should do to fix it?

Answer 1

I had a similar problem but the root cause was that my app was pointing to the old dev database which had exceeded it’s limit of 10,000 rows.

Although I created a new Basic db and backed everything up, the app was still pointing the old dev DB.

heroku pg:info

Check to see the rows: 10300/10000 (then you have a problem)

You will need to

1) Create new DB with more rows (Basic or the “Production” ones -> Heroku seems to be forcing an upgrade to make more money errrrrr)

2) backup the old DB using pgbackups: heroku pg:backups:capture SMALL_DB_NAME

3) restore the backup to the new DB: heroku pg:backups:restore BACKUP_ID BIG_DB_NAME (see links below for more details)

4) PROMOTE the new DB to the primary for the app: heroku pg:promote BIG_DB_NAME

can always utilize:

heroku maintenance:on (to disable the app while updating)

heroku maintenance:off

heroku pg:info (to check the status)
