bug: erroronous ret-value for system() call in 2.6-kernel

Hi!

 Had a curious problem with postgresql 7.0.3. Could create a DB if I run
kernel 2.4 but not in 2.6. Had a look in
/src/backend/commands/dbcommands.c and finaly found out that you use an
errorounous ret value from the system()-call. You checked for: if
(system(buf) != 0)

.. I changed those lines to if (system(buf) != -1 ) and it worked. (Thanks
to "man 3 system"
