This occurs when you’re trying to connect to a database with credentials that no longer exist. $ heroku pg:info -app sushiįollowing HEROKU_POSTGRESQL_LAVENDER (DATABASE_URL)įATAL: role “role-name"… FATAL: role "u8akd9ajka" is not permitted to log in (PG::Error) Each follower has a “Behind By” entry that indicates how many commits the follower is behind its master.
You can find out the current number of commits a follower is behind by using heroku pg:info. This is a transient problem and Postgres should automatically recover. Replication from a primary database to a follower was interrupted either because of a transient network error or because SSL failed to renegotiate. FATAL: could not receive data … FATAL: could not receive data from WAL stream: SSL error: sslv3 alert unexpected message A discussion on handling connections in a Rails application can be found here. To resolve this error, close some connections to your database by stopping background workers, reducing the number of dynos, or restarting your application in case it has created connection leaks over time. This occurs on Hobby Tier (hobby-dev and hobby-basic) plans, which have a max connection limit of 20 per user. FATAL: too many connections for role FATAL: too many connections for role ""
If you are seeing this error message, you may wish to reach out to Heroku support as the underlying cause may require an engineer to resolve. If you are seeing this only intermittently, Connect will detect the error and retry the sync operation shortly thereafter. This error can happen as a result of one of several intermittent network connectivity issues. If you are not seeing your application’s backtrace, you may need to ensure that you are, in fact, logging to stdout (instead of a file) and that you have stdout sync’d. Postgres noticed that the client (your application) disappeared without ending the connection properly, and logged a message saying so. Your application happened to crash while connected to Postgres, and did not clean up its connection to the database. Heroku: State changed from up to crashedĪlthough this log is emitted from Postgres, the cause for the error has nothing to do with the database itself.

Postgres automatically puts a checkpoint in the transaction log every so often. LOG: checkpoint starting and the corresponding LOG: checkpoint complete statements are part of Postgres’ Write-Ahead Logging (WAL) functionality. LOG: checkpoint starting… T17:41:42+00:00 app: LOG: checkpoint starting: time Queries are typically optimized by adding indexes to avoid sequential scans of the database. Ideally, frequently used queries should be optimized to require less than 10 ms to execute. Although small numbers of these long-running queries will not adversely affect application performance, a large quantity may. Queries taking longer than 2 seconds are logged so they can be identified and optimized. LOG: duration: 3.565 s … u8akd9ajka LOG: duration: 3.847 s statement: SELECT "articles".* FROM "articles".

They are not available on hobby-tier databases. You can isolate Heroku Postgres events with the heroku logs command by filtering for the postgres process. Heroku Postgres logs to the logplex which collates and publishes your application’s log-stream.
