Testing the latest features or bug fixes in PostgreSQL can easily be done by pulling the latest commits from the git repository and compile PostgreSQL from source code. I am doing that frequently on my local sandbox VM but this becomes limited when I need more CPUs or more memory. This is where the public cloud really shines, as you can easily deploy new VMs, do your tests and get rid of it afterwards with just a view clicks or commands. Bringing up a Debian VM in AWS, which already has the latest development snapshot up and running is something that can be done quite fast.
Your VPC should already be configured (or just use the default one) and if you want to connect from outside AWS you’ll need a public IP address:
Once it is running grab the public IP address and connect (the user for Debian is “admin”, not “ec2-user”):
[email protected]:~$ ssh -i /home/dwe/Documents/aws/dwe-key-pair.pem [email protected] The authenticity of host '126.96.36.199 (188.8.131.52)' can't be established. ECDSA key fingerprint is SHA256:E/W08OSWhym0k2SVQafxu3rCljqEVg/VC744sz3ilog. Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added '184.108.40.206' (ECDSA) to the list of known hosts.

Updating the OS to the latest release is always something I am doing as the first step:
[email protected]:~$ sudo apt update && sudo apt dist-upgrade -y
Install all packages you need for the compilation from source code (and some more in the list below):
[email protected]:~$ sudo apt install libldap2-dev libpython-dev libreadline-dev libssl-dev bison flex libghc-zlib-dev libcrypto++-dev libxml2-dev libxslt1-dev tcl tclcl-dev bzip2 wget screen libpam0g-dev libperl-dev make unzip libpam0g-dev python libsystemd-dev sudo llvm-7 llvm-7-dev clang pkg-config gcc g++ liblz4-dev pkg-config git -y
Configure the OS group and user you’ll use for the PostgreSQL installation:
[email protected]:~$ sudo groupadd postgres [email protected]:~$ sudo useradd -g postgres -m -s /bin/bash postgres
Clone the PostgreSQL git repository:
[email protected]:~$ sudo su - postgres -c "git clone git://git.postgresql.org/git/postgresql.git" Cloning into 'postgresql'... remote: Enumerating objects: 836887, done. remote: Counting objects: 100% (836887/836887), done. remote: Compressing objects: 100% (121635/121635), done. remote: Total 836887 (delta 719772), reused 828577 (delta 712107), pack-reused 0 Receiving objects: 100% (836887/836887), 255.06 MiB | 32.09 MiB/s, done. Resolving deltas: 100% (719772/719772), done.
This is the small script that will do all the work for us:
[email protected]:~$ sudo su - postgres [email protected]:~$ cat compile.sh #!/bin/bash rm -rf /home/postgres/pgdata cd /home/postgres/postgresql git pull make distclean ./configure --prefix=/home/postgres/pgdev make -j4 all make install cd contrib make -j4 install /home/postgres/pgdev/bin/initdb -D /home/postgres/pgdata /home/postgres/pgdev/bin/pg_ctl -D /home/postgres/pgdata start -l /dev/null /home/postgres/pgdev/bin/psql -c "select version()"
Happy testing 🙂
