How to install PostgreSQL 11.5 on Ubuntu Server?

Question

PostgreSQL

Hello! They gave me the task of installing and configuring PostgreSQL 11.5 + PostGIS on Ubuntu Server 18.04, in these matters I am almost zero. I found a lot of installation manuals, but how to specify the 11.5 version when installing PostgreSQL?
I would be grateful for any help!

Answer 1

You don't need exactly 11.5. Set the current minor - 11.8 or on Thursday it will already be 11.9.
Where a specific minor is really needed for some vague purposes, the task will not be assigned to a zero student, but, for example, there will be its own internal repository with the necessary compiled packages.
Minor releases of postgresql contain only bug fixes and security fixes. Searching for long-fixed bugs is not the most useful thing you can think of.
