I get this error message: table tid from new index tuple (32586,21) overlaps with invalid duplicate tuple at offset 120 of block 4398 in index "aacorrections_tcpreading_idx"
from an update query of the update table 1 set columnx = ‘yes’ where table1.xmlid in (select xmlid from table2) I have no idea what is going on or how to deal with it and will be grateful for advice
