Installing Pg Admin 4 on nginx unbutu 20.04 - postgresql

I'm having trouble finding any documentation of how to install and configure pgadmin4 to work with nginx on ubuntu 20.04, I only managed to find tutorials for apache.
I'm very new to nginx, can you guys help with a link to some documentation or tutorial on how to do this?

It sounds a bit like you are attempting to connect to your database on a production server, from within that server... With PgAdmin this is not needed. You can simply install locally on your system like this:
https://linuxhint.com/install-pgadmin4-ubuntu
And then just remote into the server like so:
https://www.pgadmin.org/docs/pgadmin4/development/connecting.html#connecting-to-a-server
I would argue that it is also a smarter approach to house the pgadmin connection locally as you do not need a visual approach to your databases in the production instance in most cases.

how to create postgresql server on rhel7 linux vm in gcp

I am actually planning to have a PostgreSQL instance on rhel7 linux vm running on google cloud platform,
Can you let me know the process for the same.
One more query is it ok to install postgresql on vm rather than going for a cloud sql instance on gcp?
Thanks,
Moin.
Just go to the PostgresSQL official downloads page for redhat and install the software.
You can get the RPMs there if you need to do an air-gapped installation.
You'll need to configure postgres later. See Posgres docs Chapter 18. Server Setup and Operation.

ASP NET CORE deployment can't access my database on Postgresql

I am using asp net core 2 developed a web application and deployed in Ubuntu 16.04 which is running well when I go to browser. Every tabs on my website is working but when I try to log in with my account it loads for some time and shows error page. I don't know what's wrong here :( I am guessing it is because of I didn't configure remote connection to Postgresql properly.
My question is: should I install Postgresql to my server (which is Ubuntu 16.04) and copy all my data there? Or should I continue remote connetion to database? What would be a good way?

What is the difference between pgAdmin and Postgres.app?

After reading official websites as well as conducting Google research I still do not clearly understand how pgAdmin and Postgres.app relate to one another?
For example, I can simultaneously run two different local postgres servers on different ports from both pgAdmin and Postgres.app, which is confusing. I thought that those application depend on one another, but it does not seem so.
Postgres.app is a full-featured PostgreSQL installation packaged as a standard Mac app. It sets up a PostgreSQL database server on your computer when you install it.
PgAdmin is graphical user interface administration tool for PostgreSQL. It is a client tool for working with existing local or remote PostgreSQL servers. It does not include a PostgreSQL database server.

PostgreSQL default cluster?

I am running PostgreSQL 9.3 on Ubuntu 14.04 LTS. I didn't remember creating a cluster but directly went to create database.
Using pg_lsclusters, I found that I have a cluster as following with my db
Ver Cluster Port Status Owner Data directory
9.3 main 5432 online postgres /var/lib/postgresql/9.3/main
I was reading the PostgreSQL documentation but couldn't find relevant info.
I have the following questions:
Does PostgreSQL automatically create default cluster? And if so, is it good practice to use it?
Does PostgreSQL also automatically start the default cluster? I never started but its status is online and I can see it in system-monitor.
Thanks for any clarifications!
You're really asking about "PostgreSQL on Debian or Ubuntu", as it's the packaging and wrapper utilities doing this, not PostgreSQL its self.
See the PostgreSQL help on the Ubuntu community wiki for information. This mostly applies to Debian too, since it uses the same style of packaging for PostgreSQL.
To your specific questions:
Does PostgreSQL automatically create default cluster? And if so, is it good practice to use it?
Strictly pg_wrapper, the Ubuntu/Debian tool that manages PostgreSQL installs, creates it. Yes, it's fine to use it and there's generally not much reason not to.
Does PostgreSQL also automatically start the default cluster?
This depends on your operating system and its PostgreSQL packages, not on PostgreSQL its self. For information on how to configure what starts on Ubuntu, see Boot Howto - Ubuntu Community Wiki.

ZendServer CE - change database type?

I am using the trial version of the Zend Server edition. From all the videos/documentation supposedly you are able to change the database version from SQLITE to MySQL, but all I get when deploying an application on Zend Server is to set the Host, Database name, username and password?
Just install mysql on your system and use it. ZendServer does not care what database engine you use. When installing Zend Server it is supposed to ask if you want to install mysql (possibly you have to chose manual installation or custom or extra stuff) you might of mised that option so perhapds reinstalling is the simpler solution.
But really, you should be able to just install mysql and start using it.
