Describe the Bug

Table:

export const logs = pgTable(
  'logs',
  {
    id: serial('id').primaryKey().notNull(),
    bookId: integer('book_id').references(() => books.id),
    courseId: integer('course_id').references(() => courses.id),
    metadata: text('metadata')
  },
  (table) => ({
      courseIndex: index('idx_logs_course_id').on(table.courseId),
      bookIndex: index('idx_logs_book_id').on(table.bookId)
    })
);

Then I get a deprecation warning on pgTable, and when I check the docs I see a new syntax for indexes/unique-constraints/etc. namely:

export const logs = pgTable(
'logs',
{...},
(table) => [{
      courseIndex: index('idx_logs_course_id').on(table.courseId),
      bookIndex: index('idx_logs_book_id').on(table.bookId)
    }]
)

Note the difference in the return value of that last argument, it's an array. Then if I run a migration, the SQL deletes indexes/constraints/etc.
SQL migration generated with drizzle-kit generate

DROP INDEX "idx_logs_course_id";
DROP INDEX "idx_logs_book_id";

Correct usage is

export const logs = pgTable(
    'logs',
    {...},
    (table) => [
        index('idx_logs_course_id').on(table.courseId),
        index('idx_logs_book_id').on(table.bookId)
    ]
)

Correct usage is

export const logs = pgTable(
    'logs',
    {...},
    (table) => [
        index('idx_logs_course_id').on(table.courseId),
        index('idx_logs_book_id').on(table.bookId)
    ]
)

Thanks, but could you also send me a link to the documentation where that is done?
