I've seen this problem (and others) in a high-load environment.  Not
Slony related though.

I wrote a small tool to check btree index files for consistency problems
such as this one, by parsing pg_filedump output.  I've seen strange
things such as index pointers pointing to pages that shouldn't have been
pointed to; mismatching sibling pointers; and others.

Do you have a copy of the broken index file?
