It isn't: zlib was only linked against the backend to simplify the build
process. In 8.2devel this has been corrected:

% ldd postgres
    libcrypt.so.1 => /lib/libcrypt.so.1 (0x00002aaaaabc2000)
    libresolv.so.2 => /lib/libresolv.so.2 (0x00002aaaaacf5000)
    libnsl.so.1 => /lib/libnsl.so.1 (0x00002aaaaae0a000)
    libdl.so.2 => /lib/libdl.so.2 (0x00002aaaaaf21000)
    libm.so.6 => /lib/libm.so.6 (0x00002aaaab024000)
    libc.so.6 => /lib/libc.so.6 (0x00002aaaab1a9000)
    /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)

See much discussion on this topic in the -hackers archive, and the fix
implemented by Martijn and Tom:
