Command `postgres --version` shows incorrect version installed

Question

I recently wanted to upgrade my Postgres version from 14.2 to 15.

The first thing I did, was delete all postgres related directories:

michael@local var % postgres --version postgres (PostgreSQL) 14.2 michael@local var % pwd /usr/local/var michael@local var % ls cache homebrew mongodb postgres.old postgresql@13 db log postgres postgresql@12 run michael@local var % rm -rf postgres postgres.old postgresql@12 postgresql@13 michael@local var % 

Then, I downloaded Postgres.app from their official website. The app is up and running, everything is working as expected. The installed version seems to be version 15:

SELECT version(); -- PostgreSQL 15.1 on aarch64-apple-darwin21.6.0, compiled by Apple clang version 14.0.0 (clang-1400.0.29.102), 64-bit 

But when I run postgres --version in the terminal, it still returns postgres (PostgreSQL) 14.2.

michael@local var % postgres --version postgres (PostgreSQL) 14.2 

I'm worried I may have missed something.

Is something potentially broken and, if so, how can I fix it?

Answer 1

I would try

% which postgres 

most likely you have multiple copies installed, and the one that comes first in your PATH is not the one you are looking for. You can check your path with the command

echo $PATH
