Hi,
I am doing equality comparisons on type tsvector using tsvector_eq.
How come a comparison that returns true before starts returning false
afterwards ? (see results of case 1 and 3)
Regds

IIRC, Teodor fixed a number of tsvector comparison bugs in 8.1.5 ...
try updating. (You might need to REINDEX any tsearch2 indexes
afterwards, not sure.)
