I loaded 133 million rows to a wide table (more than 100 cols) via COPY.
It's always a good idea after doing a large scale data load to do a vacuum analyze on the table (or the entire database.)
I understand the need to ANALYZE (populate the histograms needed by the dynamic optimizer), but why VACUUM (which is recommended after updates and deletes).
Thanks
