v_space_used_per_tbl shows 100 pct_unsorted for 1 node cluster

[kirill-andr]

It seems that when cluster has only 1 node, the v_space_used_per_tbl view shows all tables as being 100 pct unsorted.

I imported the pct_unsorted from table_info.sql also in this repository. That fixes the computation. See attached for my version of the v_space_used_per_tbl.
