Re: pg_ctl pointing postgres 9.5.4 after installation of postgres 10

[Rajni Baliyan <saan654@xxxxxxxxx>]

Have you set the correct environment variables after upgrade?

Your environment variables are still pointing to older version.

Set PATH to PG 10 binaries and then retry.

Hi

I have updated postgres from 9.5.4 to the latest 10.4.

But after installation I am seeing 

support@platform1:/usr/bin$ ls -lah pg_ctl

lrwxrwxrwx 1 root root 34 Jun 13 08:59 pg_ctl -> /usr/lib/postgresql/9.5/bin/pg_ctl

The issue appears similiar to the one discussed here https://stackoverflow.com/a/24763074/785523.

To install postgres 10 I have followed the below steps:-

sudo add-apt-repository "deb http://apt.postgresql.org/pub/repos/apt/ trusty-pgdg main"

wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -

sudo apt-get update

sudo apt-get install postgresql-10

Then performed the data migration using pg_upgrade and then removed postgres 9.5 

Now posgres -V is also failing with the below error

support@platform1:/usr/bin$ postgres -V

The program 'postgres' is currently not installed. You can install it by typing:

sudo apt-get install postgres-xc

Can someone let me know what is wrong and how can I fix it?
