Re: What generates pg_config.h?

Distro and version: Ubuntu 16.04 LTS.

If memory serves, I installed 9.5 using synaptic and 9.6 using apt-get,
where I followed the instructions from this site:
https://www.postgresql.org/download/linux/ubuntu/

I also have an anaconda installation of postgresql, but that is a version
less than 9.6.

Here are the results for postgresql using dpkg-query -l
