Description:
Given a column of 1000-dimension cubes the following triggers an error:
CREATE INDEX ktest ON items USING gist(embeddings);
ERROR: index row size 8016 exceeds maximum 8152 for index "ktest"
The error message appears to be out of order - the index row size reported
is smaller than the maximum.
