Let's review:
What we install is
libpq.so.5.8 (actual file)
libpq.so.5 -> libpq.so.5.8
libpq.so -> libpq.so.5.8
The second one is the one used at run-time, looked up by SONAME.
The third one is the one used at build time, because -lpq means look for
libpq.so.
If we instead installed
libpq.so.5 (actual file)
libpq.so -> libpq.so.5
nothing would effectively change.
