PostgreSQL - HyperLogLog extension not found - postgresql

Question

Can someone explain in a better way (well, in a way for dummies to understand), or more correctly how to install HyperLogLog hll extension for PostgreSQL on my Mac M1 machine.
When running CREATE EXTENSION hll;
I get:
Query 1 ERROR: ERROR: could not open extension control file "/opt/homebrew/share/postgresql/extension/hll.control": No such file or directory
I am new at this, so this documentation https://github.com/citusdata/postgresql-hll did not helped me a lot.
I installed all other extensions that I need except this one..
When typing which postgres I get:
/opt/homebrew/bin/postgres
And version: postgres (PostgreSQL) 14.3
I saw about configuring PG_CONFIG but I do not understand what exactly I should be doing here?
I will appreciate the help and I hope that this post will be of use for other dummies as I. :)

Answer 1

We can simplify the script above and execute it inline by copying and pasting all of the following into your terminal:
> yes |
#!/bin/bash
# download latest release
curl -s https://api.github.com/repos/citusdata/postgresql-hll/releases/latest \
| grep '"tarball_url":' \
| sed -E 's/.*"([^"]+)".*/\1/' \
| xargs curl -o package.tar.gz -L
# extract to new hll directory
mkdir hll && tar xf package.tar.gz -C hll --strip-components 1
# build and install extension to postgres extensions folder
cd hll
make
make install
# remove hll directory
cd ../
rm -r ./hll
# connect to PostgreSQL and install extension
psql -U postgres -c "CREATE EXTENSION hll;"

Answer 2

I wrote the script for myself to get the last package and install it.
I build it by using make.
# check if Makefile installed
make -v
# download latest release
curl -s https://api.github.com/repos/citusdata/postgresql-hll/releases/latest \
| grep '"tarball_url":' \
| sed -E 's/.*"([^"]+)".*/\1/' \
| xargs curl -o package.tar.gz -L
# extract to hll directory
mkdir hll && tar xf package.tar.gz -C hll --strip-components 1
cd hll
# build and instll extension to postgres extensions folder
make
make install
# remove hll directory
cd ../
rm -r ./hll
# connect to PostgreSQL
psql -U postgres
# install extension in your DB
CREATE EXTENSION hll;
