Today I finally found some time revisit this patch.
== no relispopulated in pg_matviews ==
Client tools like pgAdmin rely on this column to display matview info:
diff --git a/src/backend/catalog/system_views.sql
b/src/backend/catalog/system_views.sql
index ddf801307eb..724a23d559f 100644

With the patch applied, pgAdmin can no longer display the properties of
a matview:
column c.relispopulated does not exist
LINE 6: c.relispopulated AS with_data,
^
HINT: Perhaps you meant to reference the column "c.relpopulated".
I will take a closer look at the code in the next few days.
Best, Jim
