@Devrim: You got the reason from @Alan.
Self compilation has the advantage of custom gcc flags like -O3 -march
-msse, etc. which can improve performance.
Building RPMs is not a task that everyone can do. It requires
extensive reading about rpmbuild and writing the specfile.
So if you install directly from source without RPM, it won't satisfy
the libpq.so dependency, so you cannot install applications using yum.
This is not the case with Arch PKGBUILD, because the PKGBUILD is just
a bash script.
