The promotion process triggers a release and restarts the app. It also creates an alternate attachment for the old primary database, assigned with a new HEROKU_POSTGRESQL_URL config var. Pg:promote updates the value of the DATABASE_URL config var with the newly promoted database’s connection string. Promote a database to be the primary for your app with the heroku pg:promote command. Pg:killall is similar to pg:kill except it cancels or terminates every query on your database. If it fails, use the -force option to issue pg_terminate_backend to drop the entire connection for that query.

Without any arguments, pg_cancel_backend is called on the query and it attempts to cancel the query.

The procpid column can then be used to cancel or terminate those queries with pg:kill. Procpid | source | running_for | waiting | query The pg:ps command queries the pg_stat_activity view in Postgres to give a concise view into currently running queries. These commands give you view and control over currently running queries. This problem is especially common with Postgres.app users, as the post-install step of adding /Applications/Postgres.app/Contents/MacOS/bin to $PATH is easy to forget. Pg_restore: input file is too short (read 0, expected 5)Īre both often a result of this incorrect $PATH problem. Pg_dump: aborting because of server version mismatch Ensure your local Postgres is working and try again.Īnd pg_dump: server version: 12.5 pg_dump version: 10.14 ! connections on Unix domain socket '/var/pgsql_socket/.s.PGSQL.5432'? ! Is the server running locally and accepting Errors such as ! createdb: could not connect to database postgres: could not connect to server: No such file or directory It’s common, however, for the wrong binaries to be loaded in $PATH. These commands rely on the pg_dump and pg_restore binaries that are included in a Postgres installation. Usage of the PGUSER and PGPASSWORD for your local database is also supported for pg:push, just like for the pg:pull command. You’ll be prompted to pg:reset a remote database that isn’t empty. To prevent accidental data overwrites and loss, the remote database must be empty. This command takes the local database mylocaldb and pushes it to the database at DATABASE_URL on the app sushi. The command looks like this: $ heroku pg:push mylocaldb HEROKU_POSTGRESQL_MAGENTA -app sushi Pg:push pushes data from a local database into a remote Heroku Postgres database. For example, to pull data from HEROKU_POSTGRESQL_RED on the app sushi, you could run heroku pg:pull sushi::RED mylocaldb. As with all pg:* commands, you can use shorthand database identifiers here.
