@vlsi Thanks for reading my input! 
I should not have said: 
> michalkoza: Instant is a moment in time in UTC.

It is not accurate - it is just default `.toString()` behaviour on this type.

This part of the article represents my point of view: https://wiki.postgresql.org/wiki/Don%27t_Do_This#When_should_you.3F_8

I think that by choosing `Instant` in the app, and `TIMESTAMP` in DB - I'm clearly saying:
"Dear database, I handle time zones on the app side. You do not have to worry about it at all"
Which I think is a super legit approach :) It is hard for me to imagine scenario in which it would be confusing or ambiguous. 

... But I have to admit that learning this:
> timestamptz records a single moment in time. Despite what the name says it doesn't store a timestamp, just a point in time described as the number of microseconds since January 1st, 2000 in UTC

does convince me that `Instant` -> `TIMESTAMPZ` is NOT a bad idea :)
