+## Alternate database providers (experimental)

+Vercel Postgres can be switched to another Postgres-compatible, pooling provider by updating `POSTGRES_URL`. Some providers only work when SSL is disabled, which can configured by setting `DISABLE_POSTGRES_SSL = 1`.

 ## Alternate storage providers
 
 Only one storage adapter—Vercel Blob, Cloudflare R2, or AWS S3—can be used at a time. Ideally, this is configured before photos are uploaded (see [Issue #34](https://github.com/sambecker/exif-photo-blog/issues/34) for migration considerations). If you have multiple adapters, you can set one as preferred by storing "aws-s3," "cloudflare-r2," or "vercel-blob" in `NEXT_PUBLIC_STORAGE_PREFERENCE`.
