If you are reading this, the answer is yes.
We just updated our Postgres version, so I'm thankful nothing went wrong.
Is the database working as expected?

I'm so happy we've upgraded to PostgreSQL 11, I can finally start using all the features under the sun βοΈ

You know that less than 2 weeks ago they released Postgres 12, so you'll have to do without some of the features under the sun π
I know, but Heroku prudently keeps that for 3 months in beta.
I guess we'll have to upgrade again next year :P
Some features were down (now good) for a few minutes:
Yes, guilty, I'm a heavy user and needed all this during your 2-minute migration window π
We could have optimized for a time where we had less traffic, like late Friday night, but since we hadn't performed this kind of upgrade before we felt like optimizing for a time where most of the team could be online and alert made sense.
The next time we need scheduled downtime (or, gasp! face unscheduled downtime) we will likely have way more users online at all times. This kind of thing isn't getting easier.
Fortnite style!
No worries at all π π
Was only reporting because I thought it could make it easier for you guys to track any improvement opportunities
Just curious why dev is using postgres vs mysql. What are the benefits?
You phrased this question like MySQL is some sort of standard and one needs a specific reason to use something else. It's not, and especially in the Ruby/Rails community many people tend to gravitate towards Postgres by default. That said for your average CRUD app written in MVC framework/language of choice, there probably isn't much practical difference between them.
You can find a relatively comprehensive comparison here:

For me the reasons I generally choose Postgres are:
Thanks for the detailed explanation! I don't come from the ROR community so Postgres is foreign to me...and I know a lot of people that fall inthe same boat. Your answer was helpful, so thanks.
workin' ;)
I don't know, am I reading this? π€¨
RDS DB Snapshot and then upgrade?
What Heroku's upgrade procedure essentially does it the following: create a follower, upgrade, switch over the follower as main DB
The downtime is required to disable processes that write to the main DB while the follower finalizes the sync and upgrades
This was our process, pretty straightforward.

Still happy it all worked as expected.
