Hi Folks,

When I attempt to create a database with PostGIS extensions, I get an
error "could not open extension control file":

  $ createdb -O ben testdb
  $ psql testdb --command="create extension postgis"
  ERROR:  could not open extension control file 
"/gnu/store/6238qjlc6cl7wld3gykcfj83ajlsrmjd-postgresql-10.5/share/extension/postgis.control":
 No such file or directory

My GuixSD system configuration includes the PostgreSQL service and the
PostGIS package, something like this:

  (packages (cons*
            ...
            postgis
            %base-packages))

  (services (cons*
            ...
            (postgresql-service)
            %desktop-services))

If I look in the store, I see "postgis.control" in a number of places,
but definitely not in the "postgresql-10.5" directory:

  $ find /gnu/store -name postgis.control
  
/gnu/store/a9bnyqpxbhskf4vz6p84k4m42li4zqc8-postgis-2.4.4/share/extension/postgis.control
  
/gnu/store/8jimyykpydhppbdbp72zr4z7l0z2fblr-profile/share/extension/postgis.control

Regards,
Ben

Thanks Julien and Gábor, I see that this patch has now been merged into
Guix and the documentation for configuring postgis is available in the
info manual under System Configuration, Services, Database Services.
I'll close this bug report now.

After modifying my service configuration, reconfiguring and running
`herd restart postgres`, I was able to create a new database and use the
`create extension postgis` command.

Folks can see the manual for details, but the configuration change is
essentially:

  (postgresql-service #:extension-packages (list postgis))

Thanks for all your work, I really appreciate this change!

Regards,
Ben
