Wrong drizzle generate with an array of text() in PSQL

I've been trying to create an array of text() using PSQL for ex. when I add the below column, drizzle generates this

"custom_selected_rules" text[] DEFAULT NOT NULL

"custom_selected_rules" text[] DEFAULT NOT NULL

"custom_selected_rules" text[] DEFAULT NOT NULL

"custom_selected_rules" text[] DEFAULT NOT NULL

but here's the schema definition

customSelectedRules: text("custom_selected_rules")
      .array()
      .default([])
      .notNull()

customSelectedRules: text("custom_selected_rules")
      .array()
      .default([])
      .notNull()

customSelectedRules: text("custom_selected_rules")
      .array()
      .default([])
      .notNull()

customSelectedRules: text("custom_selected_rules")
      .array()
      .default([])
      .notNull()

It should be

"custom_selected_rules" text[] DEFAULT '{}'::text[] NOT NULL

"custom_selected_rules" text[] DEFAULT '{}'::text[] NOT NULL

"custom_selected_rules" text[] DEFAULT '{}'::text[] NOT NULL

"custom_selected_rules" text[] DEFAULT '{}'::text[] NOT NULL

Why Drizzle doesn't do this by default? Thanks!
