pool error message

[cderv]

Something is odd with pool in the shiny app

it lacks a pool:: in the close statement

con <- pool::dbPool(odbc::odbc(), dsn =  "Postgres Dev")
onStop(function() {
  pool::poolClose(con)
})

But even after that I have the message. Don't know why. Just to let you know.

So it looks like onStop, once registered, is not re-registered? Or something like that? I'm not 100% familiar. In any case, restarting the R session with the fix you mentioned does the trick! Clearing the environment with rm(list=ls()) may help as well. I didn't test enough to be sure. Thanks!
