TL> You have enable_seqscan = off, no?
You were right, I was testing this and had it removed, but somehow I
must have hit the wrong button in pgadmin and it was not successfully
removed from the database.
After removing the enable_seqscan = off and making sure it was gone,
it is a lot faster again.
Now it takes about 469.841 ms for the select.

mea culpa, i will not do that again :-)
