Install an extension
Unless otherwise noted, supported extensions can be installed using CREATE EXTENSION syntax.
You can install extensions from the Neon SQL Editor or from a client such as psql that permits running SQL queries. For information about using the Neon SQL Editor, see Query with Neon's SQL Editor. For information about using the psql client with Neon, see Connect with psql.
Update an extension version
Neon updates supported extensions as new versions become available. Version updates are communicated in the Release notes. To check the current version of extensions you have installed, query the pg_extension table:
You can update an extension to the latest version using ALTER EXTENSION <extension_name> UPDATE TO <new_version> syntax. For example:
Extension support notes
- Neon supports the
uuid-osspextension for generating UUIDs instead of theuuidextension. - The
sslinfoextension is not supported. Neon handles connections via a proxy that checks SSL. - The
pg_cronextension is not supported. Neon scales to zero when it is not being used, which means that a scheduler that runs inside the database cannot be implemented. Consider using an scheduler that runs externally instead. - The
file_fdwextension is not supported. Files would not remain accessible when Neon scales to zero.
Request extension support
To request support for a Postgres extension, please contact us at support@neon.tech or post your request to the Neon community forum.
Custom-built extensions
Neon supports custom-built Postgres extensions for exclusive use with your Neon account. If you developed your own Postgres extension and want to use it with Neon, send a request to support@neon.tech. Please include the following information in your request:
- A repository link or archive file containing the source code for your extension
- A description of what the extension does, instructions for compiling it, and any prerequisites
- Whether an NDA or licensing agreement is necessary for Neon to provide support for your extension
Please keep in mind that certain restrictions may apply with respect to Postgres privileges and local file system access. Neon features such as Autoscaling and Auto-suspend may limit the types of extensions we can support.
Depending on the nature of your extension, Neon may also request a liability waiver.
