Hi all,

How safe is it to use the technique described by the link below with
system catalog tables to remove bloat?

(in a couple of words it is about moving tuples to the beginning of
the table with a special way of updating)

http://www.depesz.com/2010/10/17/reduce-bloat-of-table-without-longexclusive-locks/

Are there any caveats?

Thank you.
