Yes you're right. I think I misplaced some quotes.
But still, once a vector has no position, I can't add the weights.
test=# select setweight('tano'::tsvector, 'A');
setweight
-----------
'tano'
(1 row)
test=# select setweight('tano:1'::tsvector, 'A');
setweight
-----------
'tano':1A
(1 row)
Since I'm writing some helper to manipulate tsvectors I was
wondering if
a) there is any reasonable use case of adding weights to
vectors with no position
b) I missed any obvious way to add weights to tsvectors that were
initially without positions
thanks
