Interesting. This is what I get:
# cat /usr/lib/postfix/postfix-files | grep shlib
$shlib_directory/postfix-ldap.so:f:root:-:755
$shlib_directory/postfix-pcre.so:f:root:-:755

But yet, the error message did not occur any more in the last three updates of
postfix, even though I didn't change anything:

Apparently the error was fixed regardless of what's set in
/usr/lib/postfix/postfix-files.
