More importantly, the book pays special attention to topics such as monitoring roles, backup, and recovery of your PostgreSQL 10 database, ensuring high availability, concurrency, and replication.

What version is the server?

If you experience problems, then you'll need to double-check which version of the server you have. This will help you to report a fault or to consult the correct version of the manual.

How to do it...

We will find out the version by directly querying the database server:

  1. Connect to the database and issue the following command:
postgres # SELECT version();
  1. You'll get a response that looks something like this:
PostgreSQL 10.2 on x86_64-apple-darwin16.7.0,
compiled by Apple LLVM version 9.0.0 (clang-900.0.39.2), 64-bit

That's probably too much information all at once!
