Hi @PaulaG,
Thanks for chiming in. I replied to you on this thread 
Generally speaking, if you are consistently seeing symptoms of maxed out cpu/connections (below the storage limit but unable to load the Retool DB page, unable to run Retool DB queries, etc), it's worth reviewing heavier workflows/app queries and considering self-hosting your own Postgres DB. If you're unsure of whether your account has maxed out cpu or is running into a separate issue, we can investigate on our end.
