CHEATSHEET.md

This cheatsheet is for the following video that shows how to Install and Run the PostgreSQL Database server on your Andriod Phone. Watch this video for a complete Demo/Solution: https://youtu.be/7edutr-ALdc

Install Termux:

• Google PlayStore: https://play.google.com/store/apps/details?id=com.termux
• Fdroid PlayStore(Recommended): https://f-droid.org/en/packages/com.termux
• Github (latest builds): https://github.com/termux/termux-app/releases

Once termux is installed open it and use the shell for below commands

• Install PostgreSQL:

apt update && apt install postgresql

If receiving the termux repo under maintenance error watch this video for a fix: https://youtu.be/kaCkPTX3p2E

• Create directory and initialize PostgreSQL Database Cluster:

mkdir ./postgres && initdb ./postgres

this directory stores all the postgresql data and setting files.

• Start the PostgreSQL Database Server:

pg_ctl -D ./postgres start

• Login/Quit to Postgres Shell:

# Login:
psql -d postgres

# Quit:
\q

• Stop PostgreSQL Database Server:

pg_ctl -D ./postgres stop

• Other:

You can optionally create aliases to start and stop the DB server and put them in your .bashrc/.zshrc files:

alias pgstart='pg_ctl -D ./postgres start' >> ~/.bashrc
alias pgstop='pg_ctl -D ./postgres stop' >> ~/.bashrc

Then use this aliases pgstart to start the Postgres Server & pgstop to stop the Postgres Server.

You can additionally create the more databases and DB users directly from bash shell:

# Creating additonal DB:
createdb db_name

# Creating additional DB user:
createuser --superuser --pwprompt pg_user

Enjoy!!
