This is the Windows INI file format. As such, it's easy to find code
samples in almost any language that parse this format for you. For
example, Python has a core library called ConfigParser that will read
these in, and somewhere around here I even have some UNIX shell code that
parses it. There's already a PostgreSQL-related project using this
format--even on UNIX systems the odbc.ini config files look like this.

I already have a program that generates multiple postgresql.conf files
using this format around here for exactly this sort of test (compare
benchmark results with two different configurations), just never had a
reason to package it up for anybody else to use. It's trivial code if you
use the Python parser.

Putting this in XML significantly raises the bar for how complicated tools
that work on these files must be, with the implicit dependencies that go
with that. And as Andrew already pointed out, there is very little
tree-structure to this data that justifies the extra complexity.
