Hi @ohmyboroda, welcome to the forum! 
Retool does not currently provide live support outside of Office Hours. As a community, we do our best to help our members as soon as possible. But as you've experienced, it takes a few days for the Retool team to get to most questions. As you navigate our forum, you’ll often find that many issues are resolved by other community members before our team even gets to see them, showcasing the strong collaboration we’ve built together. However, issues that few or no users have encountered before naturally receive less participation from others.
Let's find a way to connect to your resource.
First of all, are you on Self-hosted Retool or Cloud? If Self-hosted, what version? Similarly, what engine version are you using for the PostgreSQL database on Amazon RDS?
