customType causing type error when performing operation on table

I have a simple customType to use the citext extension in Postgres.

import { customType } from "drizzle-orm/pg-core";

export const citext = customType<{ data: string; driverData: string }>({
  dataType() {
    return "citext";
  },
});

import { customType } from "drizzle-orm/pg-core";

export const citext = customType<{ data: string; driverData: string }>({
  dataType() {
    return "citext";
  },
});

This is fine in my table:

export const access = pgTable("access", {
  email: citext("email").primaryKey(),
});

export const access = pgTable("access", {
  email: citext("email").primaryKey(),
});

But when I try to use the table (e.g. db.select().from(access)), I get the following error:

Argument of type 'PgTableWithColumns<{ name: "access"; schema: undefined; columns: { email: PgColumn<{ name: "email"; tableName: "access"; dataType: "custom"; columnType: "PgCustomColumn"; data: string; driverParam: string; notNull: true; hasDefault: false; enumValues: undefined; baseColumn: never; }, {}, {}>; }; dialect: "pg"; }>' is not assignable to parameter of type 'AnyPgTable<{}> | Subquery<string, unknown> | PgViewBase<string, boolean, ColumnsSelection> | SQL<unknown>'.

Custom type documentation is very limited. Has something changed here or am I doing something wrong?
