Ecto / Postgres versions

The problem
Because we need to update our Postgres Databases from 9.6 to 11.x or 12.x, we need to know if our ecto and postgres deps suit the database versions.

The question
That’s where I need some help: I need to know of these libs which versions of Postgres they support.

For example:
How can I know which Postgres versions are supported by

  • ecto 3.4.5
  • ecto_sql 3.4.5
  • postgrex 0.15?

From the postgrex

  • Supports PostgreSQL 8.4, 9.0-9.6, and later (hstore is not supported on 8.4)

I must have been blind in the case of Postgrex. thx.
