Well, you've still failed to mention most all of the relevant
information, like what platform this is and what PG version.
But what the above suggests is that libxml2 is linked to a
version of libz that doesn't appear anywhere in the dynamic
linker's search path.  How did you obtain or build libxml2,
exactly?  If this is a Linux platform, I think you might have
missed out a ldconfig call or two.

my version is 8.3.3:
I found that it's part of the server.
is it said that I should build postgresql with libxml again??

I kinda doubt that, actually, because you should not have been getting
"function not found" errors in 8.3.  An 8.3 server built without XML
support should react more like this:

regression=# select xpath('foo','bar');
ERROR:  unsupported XML feature
DETAIL:  This functionality requires the server to be built with libxml support.
HINT:  You need to rebuild PostgreSQL using --with-libxml.

In any case the error you're showing us suggests that the libxml
installation is broken, not PG itself.

You still haven't told us the platform...

googling gzopen64 throws up a whole lot of hits - most of them were
debian/ubuntu and boiled down to some problem with versions of libz.so

klint.
