When I copy some long string like json from a debugger, and want to look at it properly formatted it starts off encoded with /n and /t characters, etc.

I usually go:

• Replace (Normal) /n -> qqqq
• Replace (Extended) qqqq -> /n

Is there some trick to do this in one step?

Had a long series of failed prints, tried levelling, replacing parts, nothing worked.

Finally by chance I noticed that the LED matrix had burnt out/broken LEDs.

But where can I get a replacement? Can you do one module at a time or do I need a whole new unit?

Usual story - joined a startup and their production database is a single instance RDS running 11.3.

We can't upgrade or scale or even change configuration without taking the database offline. We want to move everything to an Aurora Postgres compatible cluster that can scale horizontally.

What options do we have? I've used Bucardo in the past to do one-way sync, but how is it at multi-master replication? What would you use for this task?
