## Description
In Postgres, localized blocks or arrays that contain other array / block
/ relationship fields were not properly storing locales in the database.
Now they are! Need to check a few things yet:
- Ensure test coverage is sufficient
- Test localized array, with non-localized array inside of it
- Test localized block with relationship field within it
- Ensure `_rels` table gets the `locale` column added if a single
non-localized relationship exists within a localized array / block
Fixes step 6 as identified in #7805
Dedicated adapter for Vercel Postgres
- Uses the `@vercel/postgres` package under the hood.
- No `pg` dependency, speeds up invocation
- Includes refactoring all base postgres functionality into a
`BasePostgresAdapter` type, which will ease implementation of [other
adapters supported by
drizzle-orm](https://orm.drizzle.team/docs/get-started-postgresql)
## Usage
```ts
import { buildConfig } from 'payload'
import { vercelPostgresAdapter } from '@payloadcms/db-vercel-postgres'
export default buildConfig({
db: vercelPostgresAdapter({
pool: {
connectionString: process.env.DATABASE_URI,
},
}),
// ...rest of config
})
```
### Automatic Connection String Detection
Have Vercel automatically detect from environment variable (typically
`process.env.POSTGRES_URL`)
```ts
export default buildConfig({
db: postgresAdapter(),
// ...rest of config
})
```
Supports `hasMany` upload fields, similar to how `hasMany` works in
other fields, i.e.:
```ts
{
type: 'upload',
relationTo: 'media',
hasMany: true
}
```

Allow a compound index to be used for upload collections via a
`filenameCompoundIndex` field. Previously, `filename` was always treated
as unique.
Usage:
```ts
{
slug: 'upload-field',
upload: {
// Slugs to include in compound index
filenameCompoundIndex: ['filename', 'alt'],
},
}
```
## Description
Fixes#7492
In order to run createMigration, we need to read in the previous
snapshot file if one exists. When that snapshot was generated from an
older version of drizzle-kit, we have to first migrate it up match the
latest version for drizzle to generate the new migration. This change
adds in the call to check the version and migrate the snapshot if
needed.
