Pool runs dry after some errors

After a few failed queries, every request hangs waiting for a database connection. What is the bug?

const client = await pool.connect()
const res = await client.query(sql, params)
client.release()
return res.rows

A.The pool must be created inside each requestB.client.release must be called before the queryC.If query throws, release never runs; put it in finallyD.pool.connect returns a new database every time
