How and what we'd choose between patroni, stolon, repmgr for out HA Postgres
While doing development of one of our project we were asked to build HA database using Postgres, geographically distributed.
First our choice was obvious, we started to work with big 3 cloud providers, but soon it was quite understand that everything costs big enough for us. Also there were a bunch of incompatibilities with unsupported extensions as well as londiste replication we were heavily used.
I will talk about why we chose patroni, what types of problem we faced with and patroni's special features can dramatically simplify deploy and everyday usage.
