I am trying to run MongoDB by running brew services start mongodb-community#4.2 but I am getting the error that you see below:

Error: Unknown command: services
jaimes-mbp:SMR jaimemontoya$
Isn't brew the command, and services only a parameter? I am not understanding why the error says that services is an unknown command. Thank you.
UPDATE 1: I see two warnings when I try to run brew install mongodb-community#4.2 again. Maybe that has something to do with the problem?:
jaimes-mbp:SMR jaimemontoya$ brew install mongodb-community#4.2
Warning: mongodb/brew/mongodb-community-4.2.3 already installed
Warning: You are using OS X 10.15.
We do not provide support for this pre-release version.
You may encounter build failures or other breakages.
UPDATE 2: When I use mongo, it is doing something:
jaimes-mbp:SMR jaimemontoya$ mongo
MongoDB shell version v4.2.3
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb

jaimes-mbp:SMR jaimemontoya$
Maybe I do not need to use brew services start mongodb-community#4.2? I thought it was necessary to run MongoDB Community Edition.
UPDATE 3: I run ps aux | grep -v grep | grep mongod and it returns nothing. I am trying to verify that MongoDB is running, so I am searching for mongod in my running processes but it returns nothing, meaning that MongoDB is not running I guess.
UPDATE 4: See what happens when I run brew doctor --verbose:
Warning: You are using OS X 10.15.

Warning: Your Homebrew is outdated.

Seems like you are facing issue with brew.
Run brew doctor --verbose to check if the brew is working fine.
And then brew update to update the brew version.
After this run, brew services list to display all the services in the brew.
If you see mongodb-community#4.2 there in the list, then run brew services start mongodb-community#4.2
It should work.
I followed the advice MikeMcQuaid provided at https://github.com/Homebrew/brew/issues/3665:
You need to uninstall and install Homebrew using
https://github.com/Homebrew/install
As explained at https://github.com/Homebrew/install, I first ran /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)". After that I ran /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)".
Then I ran this:
jaimes-mbp:SMR jaimemontoya$ brew tap mongodb/brew

I modified the code to work. I identified that the main issue is mongodb-clients which causes failures of monogdb. Also your command db.createUser is invalid and will lead to failure as well. I did not fix that, as its not related to your issue about connection refused. You can make new question why your db.createUser is incorrect (I don't know how to fix that, its mongodb specific).

I tried the suggested fix missing too but didn't work.
How can I install a postgresql package successfully? And mainly how can I get the $psql command to give me the desired output showed in the picture?
(Edit) I tried the first answer's suggestion:
vagrant#precise64:~$ apt-get update
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)
E: Unable to lock directory /var/lib/apt/lists/
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
Then tried the solutions mentioned here :

vagrant 1144 0.0 0.2 11676 948 pts/0 S+ 18:59 0:00 grep --color=auto apt
I don't understand so I don't know what's next.
looks like you had some trouble installing several packages 404 Not Found.
Do sudo apt-get update and then retry the install.
I'm trying to upgrade postgres locally so I don't get a version mismatch error. This is what i do:

I'm at a loss - any idea what the problem is please?
Just a guess but I guess you've not installed postgresql. In order to use the pg_dump you must have installed this, or if you do have it already and I'm wrong try reinstalling it like so:
bash-4.3# apk del postgresql

As you can see from above pg_dump is working because it is in the postgresql package even though as listed on alpine packages site it should be within the postgresql-client package as shown here but it doesn't work unless postgres is installed. If you can't have a full postgres installation, I recommend this workaround which is a bit unclean, install postgres, backup the pg_dump binary, uninstall postgres then restore pg_dump like so:
bash-4.3# apk add postgresql
