Bug reference: 15306
Logged by: Ding Xiang Fei
Email address: dingxiangfei2009(at)gmail(dot)com
PostgreSQL version: 11beta2
Operating system: NixOS
Description:
This is an improvement suggestion. In the configure script,
https://github.com/postgres/postgres/blob/master/configure.in#L896
this part uses `xml2-config` program to find the `libxml2` headers.
It would be more appropriate to use pkg-config program to search `libxml2`
headers.
