DEBUG strings

Hi,

I've installed a 7.0.3 PostgreSQL version on a new computer (B):
    I've already compiled and installed PostgreSQL on my old computer
(A),
    so I've mounted the directory from (A) to (B) and I've run "gmake
install"
    from (B).
    I've assigned $PGPATH and $PGLIB, ldconfig has added the $PGLIB
libraries,
    and I've initdb successfully.
    I've created my users and some db.
    Then I've restored some db dumps from (A) to (B) without any
problem,
but "vacuum" from any db gives me following output:

I would like to know if I've done something wrong, or how I can
understand this event.


Thank you in advance,                                    \fer
