[postgis-users] Slow delete of duplicate rows

[DrYSG]

One point I might not have made clear. The reason I want to remove duplicates
is that the column "data_object.unique_id" became non-unique (someone added
duplicate rows). So I added the bigSeriel (idx) to uniquely identify the
rows, and I was using the SELECT MIN(idx) and GroupBy to pick just one of
the rows that became duplicated.

I am going to try out some of your excellent suggestions. I will report back
on how they are working.
