I have worked around the Tsearch2 migration (we used the contrib module) without too much hassle, but find myself stuck at an unexpected point - I get a duplicate key violation for the primary key on one of my tables: Maybe there actually is a duplicate key in the source DB --- have you checked? There were some bugs in early 8.2.x releases that could possibly allow that to happen. regards, tom lane
