As I told Tom, the "test" DB has this issue; the production and test1 DBs
are fine; I should have thought to check those first... Sorry for the
noise.

Thanks for these links... They look very interesting. Someone on this
list suggested Practical SQL by Anthony DeBarros which we're working
through... He should see sales from all over the US now.... :)
We were working with a python script (using INSERT) someone wrote a couple
years ago; with my version using COPY[1], imports have gone from 2+ hours
to under a minute each for 8M and 33M row files. If the above links help
even more that will be amazing!! THANK YOU!!
[1] the script I sent is just a test script I threw together to check out
COPY features -- only started; but well impressed.
