test=# CREATE INDEX idxFTI_idx ON wikipedia USING gist(vector);
CREATE INDEX
Time: 416122.896 ms

so about 7 minutes - sounds very reasonable

test=# CREATE INDEX idxFTI2_idx ON wikipedia USING gin(vector);
CREATE INDEX
Time: 52681605.101 ms

I'll look at this,  but GiST time creation is suspiciously small.
Can you test on smaller table, for example with 100000 records and if results are repeat, pls, send to me test suite...
