It's an issue with the linker. I seem to remember that 8.1 uses the --as-needed flag to ld, which means it will only link the libraries that each executable actually uses. Hmm, poking my build, this doesn't seem to be the case: $ ldd `which postgres` linux-gate.so.1 => (0xffffe000) libz.so.1 => /usr/lib/libz.so.1 (0x41c54000) libreadline.so.5 => /lib/libreadline.so.5 (0xb7f51000) libcrypt.so.1 => /lib/tls/libcrypt.so.1 (0xb7f23000) libresolv.so.2 => /lib/tls/libresolv.so.2 (0x41c6a000) libnsl.so.1 => /lib/tls/libnsl.so.1 (0x41c25000) libdl.so.2 => /lib/tls/libdl.so.2 (0x4118f000) libm.so.6 => /lib/tls/libm.so.6 (0x41153000) libc.so.6 => /lib/tls/libc.so.6 (0x41019000) libncurses.so.5 => /lib/libncurses.so.5 (0xb7ee0000) /lib/ld-linux.so.2 (0x41000000) This is a fairly recent 8.1, maybe post-beta1. Not sure what happened. I certainly don't see the --as-needed in LDFLAGS: $ pg_config | grep LDFLA LDFLAGS = -Wl,-rpath,/pg/install/00orig/lib LDFLAGS_SL = -- Alvaro Herrera -- Valdivia, Chile Architect, www.EnterpriseDB.com "¿Que diferencia tiene para los muertos, los huérfanos, y aquellos que han perdido su hogar, si la loca destrucción ha sido realizada bajo el nombre del totalitarismo o del santo nombre de la libertad y la democracia?"
