Since I am investigating HA with PostgreSQL right now and have bitter experience of Pacemaker 'HA' instances that have been anything but, I am looking at Amazon Aurora and Microsoft's (in preview) Azure database for PostgreSQL offerings. I would really appreciate any insight from others who are already using them (we intend to do some PoC work shortly).
Our dev team also came up with some pertinent questions, which we have put to both companies, but if anyone else can comment from experience that would be fantastic:
* Is the product a fork of PostgreSQL or a wrapper round the current version?
* Will the DB engine keep in lock-step with new PostgreSQL releases or might they diverge?
* If the DB engine keeps in lock-step, what’s the period between a new version of PostgreSQL being released before its incorporated in the live product?
* When new versions of Amazon Aurora/Azure DB for PostgreSQL are released will our live instance get automatically updated or will we be able to choose a version?
