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.
We will find out the version by directly querying the database server:
- Connect to the database and issue the following command:
postgres # SELECT version();
- 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!
