Oy vey ... I hope this is a read-mostly table, because having that many
indexes has got to be killing your insert/update performance.
I see that some of the revop indexes might be considered relevant to
this query, so how exactly have you got those opclasses defined?
There's built-in support for reverse sort as of CVS HEAD, but in
existing releases you must have cobbled something together, and I wonder
if that could be a contributing factor ...
