Some more (useless) info.
objdump -x /lib/*.so /usr/lib/*.so /lib/i686/*.so /usr/kerberos/lib/*.so
/usr/local/pgsql/bin/* /usr/local/pgsql/lib/*.so | grep lemmatize
reviels only one lemmatize symbol.
The offending address 0x02d10000 is not mapped anywhere in the address
space according to /proc/<pid>/maps.
Nice that the coredump is 522MB ;)
