# Which Problems Are Solved
When starting Zitadel with Postgres version 18, setup fails with the
following error:
`level=error msg="migration failed" caller=".../cmd/setup/setup.go:373"
code=0A000 detail= error="ERROR: partitioned tables cannot be unlogged
(SQLSTATE 0A000)" hint= message="partitioned tables cannot be unlogged"
name=34_add_cache_schema severity=ERROR`
# How the Problems Are Solved
- Modify setup step 34 to ensure compatibility with PostgreSQL 18 by
changing the creation of the partitioned tables to`LOGGED` tables but
keep the partitions `UNLOGGED`.
- Added an additional setup step which alters the table persistence of
the partitioned tables to `LOGGED`.
# Additional Changes
- Bumped Postgres compatibility to version 18 in docs.
- Ensure default partitions for cache tables
## Additional Context
- closes https://github.com/zitadel/zitadel/issues/10712
- backport to v4
- migration from PostgreSQL version 17 to 18 was verified using
`pg_dumpall` and restoring the created backup file
- and new setups using PostgreSQL version 18 directly
