Hi,
In our GIS team (small team of 10, local government, province level) we
use a lot of SQL in collaboration with Gradle/GRETL and Jenkins for our
automated data flows and statistics. It is amazing how much analysis and
data aggregation you can do with SQL only - without having to touch QGIS
or ArcGIS or any other so called "business intelligence" tools (that are
often quite expensive).
Every new employee that wants to join our team has to have SQL knowledge
- that's a prerequisite - or they wouldn't get the job. Most of our
employees are not programmers though.
I also teach PostgreSQL/Postgis training courses (2-3 days usually) - a
lot of the participants are not programmers but still manage to do
analysis with SQL. Typical course participants are scientists, people
working at engineering companies or government.
So - I do think there is a significant number of people who use SQL, but
aren't programmers.

I doubt whether PostGIS has any direct value whatsoever for desktop application
users. At a very minimum, using PostGIS directly requires a knowledge of
SQL. In fact, the more knowledge of SQL a user has, the more powerful PostGIS
will be. SQL is usually taught in a database course which, in many computer
science curriculums, is taught in the second or third year, not to end users in
another occupation.
Business intelligence systems such as Power BI and Tableau can connect directly to PostGIS data bases and provide end user commands and operations for querying and modifying those databases. GIS systems such as ArcGIS and QGIS provide similar capabilities. End users can get nearly all of the power of PostGIS without having to learn anything outside of the business intelligence system or the GIS system.
PostGIS is probably best reserved for people who have a programming background
and whose jobs or avocations involve doing things that are difficult or
impossible to do in existing business intelligence or GIS applications. There
seem to be more than enough people like that to keep the PostGIS developers
quite busy.

Though we have got some good examples of serving data to wider business intelligence community, we are still interested in finding excellent, compelling examples for showing the value of PostgreSQL/PostGIS as a data service to desktop application users.
I just wonder whether there are excellent examples, for general users to appreciate?
