That's not a cheat; that's exactly the way everybody else does it.
That's how you get from a non-versioned library "-l" switch in a
makefile to a version-numbered reference in the resulting executable.
(The linker is supposed to dereference the symlink at link time.)

Then you've got a broken package. Make the symlink by hand, and file a
bug report with Oracle.

The server doesn't care about this. It's only an issue for putting
libpq into multithreaded application programs.
