Dynamic libraries can be found: libpq.so.4, libpq.so

I'm investigating the use of lazarus/postgresql for a linux desktop application.

Fresh Linux installation produce this error, when starting application

Sender=Exception
Exception=None of the dynamic libraries can be found: libpq.so.4, libpq.so

Fix is

ln -s /usr/lib/libpq.so.5 /usr/lib/libpq.so
