The nim version may be relevant here as this compiles under nim 2.0.8

import norm/[model, sqlite, pool]


proc myDb(): DbConn = open("mydb.db", "", "", "")

type User = ref object of Model
proc newUser(): User = User(id: 1)

var connPool* = newPool[DbConn](10,myDb)

proc initDb*() =
  withDb(connPool):
    db.createTables(newUser())

proc resetPool*() =
  connPool.reset()

proc closePool*() =
  close(connPool)
