1h of downtime per month means you're delivering at best two 9s of availability. again that may be fine for lots of applications but it's trivial scale, and certainly a couple orders of magnitude below what aws and cloudflare provide
taking a step back, if your application's db requirements can be satisfied by sqlite [+replication] then that's great, but that set of requirements is much narrower, and much easier to solve, than what postgres is for
