Rails is not picking up my current postgres version - ruby-on-rails

I stumbled upon following issue. I've upgraded my postgres to version #13 by running brew install postgresql#13 - this installed version 13.8. I then added paths to my ~/.zshrc (for compilers too).
Then I run source ~/.zshrc, even restarted the whole terminal and restarted my laptop. If I check my postgres version, it's 13.8 but whenever I run any of the rails commands within my project, and then double check it by running rails c & ActiveRecord::Base.connection.select_value('SELECT version()') it shows the old PostgreSQL 10.22 version, so obviously my rails is not picking up the current PG version.

Do you have any idea what am I missing?
Best,

Rails console not letting me access command history from previous console sessions

The issue: I can no longer access my command history from previous Rails console sessions - history is only available for my current console session.
I'm on macOS Sierra (10.12.2). My last app was Rails 3.2 and Ruby 2.1.6 (installed via rvm), and when I fired up a console (using rails c command from terminal), pressing the up arrow on my keyboard let me access my history from previous console sessions.
My new app is Rails 5.0.1 and Ruby 2.4.0 (also installed using rvm). When I start the console in this app, pressing the up arrow doesn't recall any commands from before.
In my home folder, the .irbrc file looks like this:
require "awesome_print"
AwesomePrint.irb!
require 'irb/ext/save-history'
My intuition is this has something to do with rvm changing something up on me, since I can't really think of what else would have changed going between my old app and newer one.
Any idea why I can't retrieve old Rails console commands from my history?
Edit:
When I start the console it gives me the following messages:
Loading development environment (Rails 5.0.1)
Cannot read termcap database;
using dumb terminal settings.
You may need to uninstall readline and then reinstall before reinstalling ruby:
brew uninstall readline
brew install readline
You may further need to include --ignore-dependencies when uninstalling if another package depends on an old version of readline, e.g. postgresql in my case.

Rake db:create fails on Library not loaded

I was running PostgreSQL 9.1, installed from Postgres (/Library/PostgreSQL/9.1) - ie not homebrew etc and on Mac OSX Leopard.
I upgraded to Snow Leopard and then immediately to Mountain Lion and had a mass of problems with gems failing to build etc, but got them fixed
Rails server crashed on startup with pg issues & I tried everything I could find but could not fix the prob - fixes included links etc, which may still persist (hence this background info might inform the solution)
I uninstalled postgresql 9.1 and installed Postgres App
Now on rake db:create I get the following:
rake aborted!
dlopen(/Users/mitch/.rvm/gems/ruby-1.9.2-p320#tme-3.2.11-mltest/gems/pg-0.17.0/lib/pg_ext.bundle, 9): Library not loaded: #loader_path/../lib/libpq.5.dylib

I'm running rvm (as u can see) and after the OS upgrade created a new gemset and installed Ruby
I've changed my path to reflect the advice of Postgresql App, after the OS upgrade I installed Xcode 5 and the command line tools as advised and I think my database.yaml file is ok
I suspect the problem might be connected with sym-links made earlier in the process, but I'm stuck to find the solution
Sounds like something has gone wrong in your Ruby installation. Try reinstalling Ruby Enterprise Edition via RVM:
rvm reinstall ree
I was experiencing the same issue with a different version of libpq. What I ended up doing is creating a link to the correct file:
sudo ln -s /Applications/Postgres93.app/Contents/MacOS/lib/libpq.5.6.dylib /usr/local/lib/
My previous answer was deleted as it wasn't originally an answer, just a confirmation of a similar issue. Hope this helps!
In the end I think this was tied up with the fact that Mountain Lion ships with Postgresql rather than MySQL as per previous OSX versions.
I couldn't make sense of the Postgres App, so I uninstalled it and also uninstalled the version of Postgresql that shipped with ML and then did a Homebrew install of the latest version of Postgresql (which places it in a different place than if you install it direct from the Postgresql site).
This seemed to straighten everything up

Problems finding ruby, rails, git after bungled PostgreSQL install

I had rails working fine for several weeks but I tried to install PostgreSQL to match Heroku and it failed to work. Now, when I open the terminal it pretend rails is not there and sets the default ruby to 1.8.7. When I start RVM it finds the right version of ruby and finds rails again and can start the server but each time I open a new shell it's back to not finding anything. Plus, the git commands don't work even after starting rvm.
I have set rvm to start by default but that doesn't work either, it has to be started manually, and it still doesn't fix the git issue.
More Detail
I am installing on Mountain Lion. This already has Postgres but the tutorial I was using suggested installing fresh using Homebrew. The trouble was the Homebrew installation installs to /usr/local/var/postgres and the installed ppstgres installs to usr/var/postgres. The system automatically uses the usr/var/postgres version, so following the tutorial I chnaged the order of usr/local/bin and usr/bin in etc/paths. That didn't help so I changed it back. Everything then went to hell so I reinstalled Mountain Lion but nothing had changed.
There are two known problems with loading RVM & default ruby:
login shell: go to terminal emulator preferences and enable login shell, sometimes it might be required to use /bin/bash --login instead.
ZSH (+ Oh-My-ZSH): go to ~/.zshrc and comment out any lines starting with: PATH= or path=(, it is still possible to use those but they need to reference itself like: PATH=$PATH:HOME/.rvm/bin or path+=( $HOME/.rvm/bin ) - which update and not reset PATH. This might be a bug in terminal emulator or ZSH ...
The git issue is explained by the reinstall of Mountain Lion which did not automatically install the command line tools. That now works. The only pain is having to load rvm every time now.

$PATH confusion Postgres and Rails on OSX Lion

Rails and all my gem files + homebrew installs have been working fine up until this point.
I ran
homebrew install postgresql
and was following the prompts pretty much as indicated in this video but it kept giving me error messages saying there is a server already running. I checked
which psql
in the terminal and it reported a
usr/bin
location rather than
usr/local/bin
indicating I was using the postgres that comes with osx not the new homebrew install.
When I attempted to start the database server I recieved an error message saying the server is already running. There is a mention of this error message in the postgres help documentation but no real working solution.
Attempting brew doctor confirmed that i needed to change my PATH in .bash_profile.
I came across this little snippet here on stack overflow for the .bash_profile edit.
export PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/local/bin
I saved the file and managed to get postgres up and running fine but then when I went to start a new rails app.
rails new blog -d postgresql
it says
Rails is not currently installed on this system. To get the latest version,
simply type:
$ sudo gem install rails
You can then rerun your "rails" command.
Any attempt to install does not work until i change the bash_profile file back to what it was before.
If I change it back postgres has the same issue again saying there is already a server running.
Also I thought it might be a launch agent or something but I don't think there are any that are set up.
I figure either something is installed in the wrong place or I have to add something to the .bash_profile?
Don't set your $PATH explicitly. You should append or prepend to it instead:
# In your .bash_profile
export PATH="/usr/local/bin:$PATH"
My guess is that you either use RVM or rbenv. If you change your path to /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/local/bin explicitly then RVM or rbenv won't be in your path.

Rails not found after Mac Update

I just ran an Update on my Snow Leopard and today when I tried to run Rails server I got the following:
Rails is not currently installed on this system. To get the latest
version, simply type:
$ sudo gem install rails
On Echo $PATH I get following:
/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/X11/bin
Update
Running the command giving above for installing rails did not do any harm. I guess updating process removed previous links of rails. the latest version of Rails and dependencies got installed and things working perfect
Try this command
which rails
and see if rails is installed. If it is, add it to your executable path
