Postgres 18 is now available
By Chris Sinjakli |
Postgres 18 is now available on PlanetScale. Starting today, when you create a new database, the default version will be 18.1. You can select a prior version using the dropdown on the database creation page.
This combined with our recent launches of $5 single-node databases and $50 Metal databases makes it the perfect platform to power your Postgres-backed applications.
What's new in 18?
The Postgres 18 release notes have all the details on what's changed since version 17. The highlights include:
- A new asynchronous I/O system that can improve query performance
- Built-in support for UUIDv7 with the
uuidv7()function - More queries can make use of multi-column indexes thanks to the new Skip Scan optimization

Upgrading from Postgres 17 to 18
We don't currently offer an automated, in-place upgrade from Postgres 17 to 18. To upgrade, create a new Postgres 18 database and perform an online migration from your existing PlanetScale Postgres 17 database using our import guides.
