Omit fields with createInsertSchema, createUpdateSchema, createSelectSchema?

[waynesbrain]

Is there a more convenient way to omit fields with these functions from drizzle-typebox? Currently I have to do this to omit a field (phash) from the schema and resulting type:

const UpdateSchema = createUpdateSchema(table, {
  updated_at: Type.String(),
});
export const UpdateRow = Type.Omit(UpdateSchema, ["phash"]);
export type UpdateRow = Static<typeof UpdateRow>;

Other things I tried that didn't work:

export const UpdateRow = createUpdateSchema(table, {
  phash: Type.Never(), // Makes prop required everywhere
  updated_at: Type.String(),
});
export type UpdateRow = Static<typeof UpdateRow>;

export const UpdateRow = createUpdateSchema(table, {
  phash: undefined, // Has no effect at all
  updated_at: Type.String(),
});
export type UpdateRow = Static<typeof UpdateRow>;

export const UpdateRow = Type.Omit(createUpdateSchema(table, {
  updated_at: Type.String(),
}), ["phash"]); // This causes infinite descent TypeScript errors.
export type UpdateRow = Static<typeof UpdateRow>;

I can see here that refinements are simply assigned with no consideration for what type of refinement is given.

It would be nice if that could be wrapped with a check for if (!TypeGuard.isNever(refinement)) { or even better if (!(key in refinements and refinement === undefined)) { ...

I started making a pull request for this, but I thought I'd check if I was missing something before spending time doing that.

i.e. if I set field: undefined as a refinement, do not add that column.
