libpq.so.4: cannot open shared object file

Ok, last hurdle (I hope) for the CentOS migration:

If you get

Starting httpd: /usr/sbin/httpd: error while loading shared libraries: libpq.so.4: cannot open shared object file: No such file or directory

starting Apache2 on CentOS, possibly after having installed later versions of Postgresql and forcing some compat-postgresql-libs, you might proceed like this:

yum remove apr-util

(this will remove httpd / Apache2 also)

then:

yum install httpd

(this will reinstall apr-util and [hopefully] fix the dependencies).

I got the hint from here, regarding the libpq dependencies:

YMMV
