Postgres Update - version mismatch error when running commands

Question

I recently updated Postgres from version 9.3 to 9.6. After the update all of my commands (such as pg_dumpall) all point to version 9.3. I get the error of version mismatch.

I found that if I change my symlink in /usr/bin to point to 9.6 it seems to work. Is there a better way to point my commands to version 9.6? Thanks you for your help!

Answer 1

The best way to do it is using the package manager of your linux distro: it ensures all symlinks are changed to the newer version. From your question it is possible to infer that the upgrade was done without using the package manager. I suggest to try to install Postgres with the package manager or give a little more information about your system so we can give you a more accurate answer.
