Using bigint primary keys results in a serialisation issue at runtime

[thekevinbrown]

Describe the bug
When you use bigint primary keys everything works until we pass the data over to the graphql reference implementation:

"message":"ID cannot represent value: 1","stack":"GraphQLError: ID cannot represent value: 1\n    at GraphQLScalarType.serialize ([project directory]/node_modules/.pnpm/[email protected]/node_modules/graphql/type/scalars.js:301:11)

To Reproduce

Create a table as follows:

CREATE TABLE test (
    id bigint GENERATED ALWAYS AS IDENTITY PRIMARY KEY,
    note text
);

Then populate some data in the table. Query the values from the table.

Expected behavior
Expected functional query response.

Actual behavior
Error

Additional context
It looks like they're not going to coerce these values for us: graphql/graphql-js#3913
