How can I create a `nulls not distinct` index in Postgres 15 for `push`?

Hi 👋 I'm having trouble to create such an index. This

  (table) => ({
    uniqueIdx: unique("mytable_uniq_idx_composite").on(table.foo, table.bar).nullsNotDistinct(),
  }),

  (table) => ({
    uniqueIdx: unique("mytable_uniq_idx_composite").on(table.foo, table.bar).nullsNotDistinct(),
  }),

somehow does not create an index that has the nulls not distinct constraint. Whereas a query like this would work.

(table) => ({
    uniqueIdx: uniqueIndex('mytable_uniq_idx_composite')
      .on(table.foo, table.bar)
      .where(sql`NULLS NOT DISTINCT`),
  }),

(table) => ({
    uniqueIdx: uniqueIndex('mytable_uniq_idx_composite')
      .on(table.foo, table.bar)
      .where(sql`NULLS NOT DISTINCT`),
  }),

However, there's a WHERE clause that breaks it.

CREATE UNIQUE INDEX IF NOT EXISTS "mytable_uniq_idx_composite" ON "mytable" USING btree ("foo","bar") WHERE NULLS NOT DISTINCT;

CREATE UNIQUE INDEX IF NOT EXISTS "mytable_uniq_idx_composite" ON "mytable" USING btree ("foo","bar") WHERE NULLS NOT DISTINCT;

@Michael Schaufelberger Hi there. Haven't seen this issue before, so it might be a bug we need to patch. Could you file an issue on the Github repo so we can keep track of this bug?
