Sorry, I mis-reported the index sizes. They are about 1/10 the size:
15 MB After the index was created.
19 MB After updating 40,422 rows.
24 MB After VACUUM FULL
27 MB After deleting 40,422 rows & again VACUUM FULL
I still have a problem that the index size grows and grows and eventually searches slow to a
crawl.
