Correct, the Singular datasets works fine on gp
and
the separable dataset works fine on gp.
But when the dataset is both *singular and separable* then it does not work on
gp, i.e., it produces an empty output with no error message or information from
the user. This is the data set called "load-data.sql".
The notebook shows that "load-data.sql" does however work with postgres.
The goal of this JIRA is to investigate the problem with the "load-data.sql"
dataset.
The issue is with the data set th

> Separated and singular data sets may produce and empty model table on
