[From same URL above]:
"For pcrc, I've never seen it.

For all pcre, we seem to have:
ambas3-gb-pcre: /usr/lib64/gambas3/gb.pcre.so
lib64pcre1: /usr/lib64/libpcre.so.1
lib64pcre1: /usr/lib64/libpcre.so.1.2.13
lib64pcre-devel: /usr/lib64/libpcre.so
postfix-pcre: /usr/lib64/postfix-pcre.so
postfix-pcre: /usr/lib64/postfix-pcre.so
prelude-lml: /usr/lib64/prelude-lml/pcre.so

Where did you dig up 'dict_pcre.so' ? Is it necessary? The referenced previous bug about the Postfix update had good feedback generally.

It looks like, it does not make problems - but I guess there is a reason for the output and we should correct it, as it might make problems somewhere.

Sure, and it is installed! As I use some pcre for filtering mails.

It was one of the warnings which rise up, when I installed the package. I guess one of those strange startup scripts of postfix emit it.

this is some of the output on install/update of postfix:

These are the essential problem.

For 'dict_pcre.so', I found a couple of old Debian posts which imply that it is installed with/by:
"Looks like PCRE doesn't included by default by Debian maintainer. You have to install it by
apt-get install postfix-pcre
File list of package postfix-pcre in wheezy of architecture amd64
/usr/lib/postfix/dict_pcre.so"

"postmap: warning: unsupported dictionary type: pcre (/usr/lib/postfix/dict_pcre.so: No such file or directory)
-
symlinking postfix-pcre.so.1.0.1 to dict_pcre.so seems to be a temporary workaround"

But Marc has installed postfix-pcre, which looks as if it should include the 'dict_' bit.
We have no sign of 'postfix/dict_pcre.so'

And yes, the permissions warning should be fixed.

Assigning to all packagers, CC'ing Stig who normally updates Postfix versions.
