A reserved/released ReservedSql prevents the main Sql from ending

Awesome library! Thanks so far. I have a small issue though... this works fine:

const sql1 = postgres(process.env.DATABASE_URL);
await sql1.end();

But this hangs indefinitely:

const sql1 = postgres(process.env.DATABASE_URL);

  const sql2 = await sql1.reserve();
  sql2.release();

await sql1.end(); // never completes

Once I have reserved/released a ReservedSql connection, the only way I can end the whole thing cleanly is to add a timeout with await sql1.end({timeout: 0.1});.

By the way, I notice that the .release method doesn't seem asynchronous, even though the example in the readme has an await. That doesn't fix this issue though.

Is this expected? Thanks!

Start by reproducing the minimal JavaScript example and inspect the connection lifecycle behind reserve(), release(), and end(). Done means a released reserved connection no longer prevents sql1.end() from completing without a timeout, with regression coverage for the reported sequence.
