### What?
### Why?
### How?
Fixes #
-->
### What?
Exposes ability to enable
[AUTOINCREMENT](https://www.sqlite.org/autoinc.html) for Primary Keys
which ensures that the same ID cannot be reused from previously deleted
rows.
```ts
sqliteAdapter({
autoIncrement: true
})
```
### Why?
This may be essential for some systems. Enabled `autoIncrement: true`
also for the SQLite Adapter in our tests, which can be useful when
testing whether the doc was deleted or not when you also have other
create operations.
### How?
Uses Drizzle's `autoIncrement` option.
WARNING:
This cannot be enabled in an existing project without a custom
migration, as it completely changes how primary keys are stored in the
database.
This PR allows to have full type safety on `payload.drizzle` with a
single command
```sh
pnpm payload generate:db-schema
```
Which generates TypeScript code with Drizzle declarations based on the
current database schema.

We also now proxy drizzle package the same way we do for Lexical so you
don't have to install it (and you shouldn't because you may have version
mismatch).
Instead, you can import from Drizzle like this:
```ts
import {
pgTable,
index,
foreignKey,
integer,
text,
varchar,
jsonb,
boolean,
numeric,
serial,
timestamp,
uniqueIndex,
pgEnum,
} from '@payloadcms/db-postgres/drizzle/pg-core'
import { sql } from '@payloadcms/db-postgres/drizzle'
import { relations } from '@payloadcms/db-postgres/drizzle/relations'
```
Fixes https://github.com/payloadcms/payload/discussions/4318
In the future we can also support types generation for mongoose / raw
mongodb results.
Currently in the `beta` docs at the bottom of [Local API Overview Import
It
section](https://payloadcms.com/docs/beta/local-api/overview#importing-it)
there is a link for _Outside Nextjs_ which incorrectly sends you to
`/docs/beta/beta/local-api/outside-nextjs` instead of
`docs/beta/local-api/outside-nextjs`.
Interestingly enough, a `Not Found` component/message is not rendered
and instead you see a blank screen.

Adds abillity to customize the generated Drizzle schema with
`beforeSchemaInit` and `afterSchemaInit`. Could be useful if you want to
preserve the existing database schema / override the generated one with
features that aren't supported from the Payload config.
## Docs:
### beforeSchemaInit
Runs before the schema is built. You can use this hook to extend your
database structure with tables that won't be managed by Payload.
```ts
import { postgresAdapter } from '@payloadcms/db-postgres'
import { integer, pgTable, serial } from 'drizzle-orm/pg-core'
postgresAdapter({
beforeSchemaInit: [
({ schema, adapter }) => {
return {
...schema,
tables: {
...schema.tables,
addedTable: pgTable('added_table', {
id: serial('id').notNull(),
}),
},
}
},
],
})
```
One use case is preserving your existing database structure when
migrating to Payload. By default, Payload drops the current database
schema, which may not be desirable in this scenario.
To quickly generate the Drizzle schema from your database you can use
[Drizzle
Introspection](https://orm.drizzle.team/kit-docs/commands#introspect--pull)
You should get the `schema.ts` file which may look like this:
```ts
import { pgTable, uniqueIndex, serial, varchar, text } from 'drizzle-orm/pg-core'
export const users = pgTable('users', {
id: serial('id').primaryKey(),
fullName: text('full_name'),
phone: varchar('phone', { length: 256 }),
})
export const countries = pgTable(
'countries',
{
id: serial('id').primaryKey(),
name: varchar('name', { length: 256 }),
},
(countries) => {
return {
nameIndex: uniqueIndex('name_idx').on(countries.name),
}
},
)
```
You can import them into your config and append to the schema with the
`beforeSchemaInit` hook like this:
```ts
import { postgresAdapter } from '@payloadcms/db-postgres'
import { users, countries } from '../drizzle/schema'
postgresAdapter({
beforeSchemaInit: [
({ schema, adapter }) => {
return {
...schema,
tables: {
...schema.tables,
users,
countries
},
}
},
],
})
```
Make sure Payload doesn't overlap table names with its collections. For
example, if you already have a collection with slug "users", you should
either change the slug or `dbName` to change the table name for this
collection.
### afterSchemaInit
Runs after the Drizzle schema is built. You can use this hook to modify
the schema with features that aren't supported by Payload, or if you
want to add a column that you don't want to be in the Payload config.
To extend a table, Payload exposes `extendTable` utillity to the args.
You can refer to the [Drizzle
documentation](https://orm.drizzle.team/docs/sql-schema-declaration).
The following example adds the `extra_integer_column` column and a
composite index on `country` and `city` columns.
```ts
import { postgresAdapter } from '@payloadcms/db-postgres'
import { index, integer } from 'drizzle-orm/pg-core'
import { buildConfig } from 'payload'
export default buildConfig({
collections: [
{
slug: 'places',
fields: [
{
name: 'country',
type: 'text',
},
{
name: 'city',
type: 'text',
},
],
},
],
db: postgresAdapter({
afterSchemaInit: [
({ schema, extendTable, adapter }) => {
extendTable({
table: schema.tables.places,
columns: {
extraIntegerColumn: integer('extra_integer_column'),
},
extraConfig: (table) => ({
country_city_composite_index: index('country_city_composite_index').on(
table.country,
table.city,
),
}),
})
return schema
},
],
}),
})
```
