Hi. Does Drizzle support DML statements when running migrations? My use case is to add a new column, populate it and then make it not null. ```sql ALTER TABLE "conversations" ADD COLUMN "channel_id" text; --> statement-breakpoint UPDATE "conversations" SET channel_id = 'some value'; --> statement-breakpoint ALTER TABLE "conversations" ALTER COLUMN "channel_id" SET NOT NULL; ``` ``` PostgresError: column "channel_id" of relation "conversations" contains null values ```
