This document will go over the key points of migrating and setting up Postgres support in Lidarr.
Lidarr v1.1.2.2890 or newer required
This guide was been created by the amazing Roxedus.
Postgres databases are NOT backed up by Lidarr, any backups must be implemented and maintained by the user
First, we need a Postgres instance. This guide is written for usage of the postgres:14 Docker image.
Do not even think about using the
latesttag!
docker create --name=postgres14 \
-e POSTGRES_PASSWORD=qstick \
-e POSTGRES_USER=qstick \
-e POSTGRES_DB=lidarr-main \
-p 5432:5432/tcp \
-v /path/to/appdata/postgres14:/var/lib/postgresql/data \
postgres:14
Lidarr needs two databases, the default names of these are:
lidarr-main This is used to store all configuration and historylidarr-log This is used to store events that produce a logentryLidarr will not create the databases for you. Make sure you create them ahead of time
Create the databases mentioned above using your favorite method - for example pgAdmin or Adminer.
You can give the databases any name you want but make sure config.xml file has the correct names. For further information see schema creation.
We need to tell Lidarr to use Postgres. The config.xml should already be populated with the entries we need:
<PostgresUser>qstick</PostgresUser>
<PostgresPassword>qstick</PostgresPassword>
<PostgresPort>5432</PostgresPort>
<PostgresHost>postgres14</PostgresHost>
If you want to specify a database name then should also include the following configuration:
<PostgresMainDb>MainDbName</PostgresMainDb>
<PostgresLogDb>LogDbName</PostgresLogDb>
Only after creating both databases you can start the Lidarr migration from SQLite to Postgres.
If you do not want to migrate a existing SQLite database to Postgres then you are already finished with this guide!
Migrating an existing sqlite3 database is unsupported, and this script may not work without modifications which we cannot assist you with. We support only new installs using postgres.
To migrate data we can use PGLoader. It does, however, have some gotchas:
--with "quote identifiers" to make them sensitive.Do not drop any tables in the Postgres instance
Before starting a migration please ensure that you have run Lidarr against the created Postgres databases at least once successfully. Begin the migration by doing the following:
DELETE FROM "QualityProfiles";
DELETE FROM "QualityDefinitions";
DELETE FROM "DelayProfiles";
DELETE FROM "Metadata";
DELETE FROM "MetadataProfiles";
Start the migration by using either of these options:
pgloader --with "quote identifiers" --with "data only" lidarr.db 'postgresql://qstick:qstick@localhost/lidarr-main'
docker run --rm -v /absolute/path/to/lidarr.db:/lidarr.db:ro --network=host ghcr.io/roxedus/pgloader --with "quote identifiers" --with "data only" /lidarr.db "postgresql://qstick:qstick@localhost/lidarr-main"
If you experience an error using pgloader it could be due to your DB being too large, to resolve this try adding
--with "prefetch rows = 100" --with "batch size = 1MB"to the above command
With these handled, it is pretty straightforward after telling it to not mess with the scheme using
--with "data only"
