=== Fixing postgresql database issue after 25.05 upgrade ===
==== Postgresql collation version mismatch ====
After upgrading you might run into an issue like this, leading to immich-server continuously failing and restarting: <syntaxhighlight>Jul 01 14:23:12 server2 immich[178592]: Postgres notice: {
Jul 01 14:23:12 server2 immich[178592]:  severity_local: 'WARNING',
Jul 01 14:23:12 server2 immich[178592]:  severity: 'WARNING',
Jul 01 14:23:12 server2 immich[178592]:  code: '01000',
Jul 01 14:23:12 server2 immich[178592]:  message: 'database "immich" has a collation version mismatch',
Jul 01 14:23:12 server2 immich[178592]:  detail: 'The database was created using collation version 2.39, but the operating system provides version 2.40.',
Jul 01 14:23:12 server2 immich[178592]:  hint: 'Rebuild all objects in this database that use the default collation and run ALTER DATABASE immich REFRESH COLLATION VERSION,>
Jul 01 14:23:12 server2 immich[178592]:  file: 'postinit.c',
Jul 01 14:23:12 server2 immich[178592]:  line: '477',
Jul 01 14:23:12 server2 immich[178592]:  routine: 'CheckMyDatabase'
Jul 01 14:23:12 server2 immich[178592]: }</syntaxhighlight>To fix this, run <code>sudo -u immich psql -d immich</code> and execute these to commands:<syntaxhighlight lang="sql" line="1">
ALTER DATABASE immich REFRESH COLLATION VERSION;
REINDEX DATABASE immich;
</syntaxhighlight>
==== Upgrading pgvecto.rs ====
If you still run into issues after restarting postgresql and immich-server services, some additional postgresql database changes might be necessary to [https://web.archive.org/web/20240910231531/https://docs.pgvecto.rs/admin/upgrading.html#upgrading upgrade pgvecto.rs table]:


Run <code>sudo -u postgresql psql</code> and execute consecutively:<syntaxhighlight lang="sql" line="1">
CREATE EXTENSION IF NOT EXISTS unaccent;
CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
CREATE EXTENSION IF NOT EXISTS vectors;
CREATE EXTENSION IF NOT EXISTS cube;
CREATE EXTENSION IF NOT EXISTS earthdistance;
CREATE EXTENSION IF NOT EXISTS pg_trgm;
ALTER EXTENSION vectors UPDATE;
SELECT pgvectors_upgrade();
</syntaxhighlight>Finally, restart postgresql and immich: <code>systemctl restart postgresql && systemctl restart immich-server</code>
