We only use this on Windows. On platforms with a decent package manager we indeed link to a shared library.
You shouldn't ever need static libraries on Windows, though. Because it searches the CWD first on its linker search path, you can just drop libpq.dll in the same directory as your binary/library and link to the stub libpq.lib .
On Mac OS X and Linux, you can use relative rpath linking. On OS X use @executable_path either at link-time or later via install_name_tool . On Linux, use $ORIGIN in your rpath. Beware of quoting issues with $ORIGIN though.
I'm not trying to block support for a static libpq, I just don't see the point.
