I'm afraid so. The weird thing is, we once tried running
VACUUM FULL followed by REINDEX and although the process
took ages to complete, it didn't seem to help either. :(
I'll post whatever debug data I'm asked for, just don't make
me run VACUUM FULL or REINDEX again please. (A full redump
is 10-20 times faster. :O)
