On RHEL6 /usr/lib64/libpq.so.5.2 is in the package "postgresql-libs";
on Ubuntu20.04 /usr/lib/x86_64-linux-gnu/libpq.so.5.12 is in the package 
"libpq5". The dev/devel packages have libpq.so as a symbolic link to
these numbered .so libraries, so I guess you need a non-devel package
like libpq or libpq5.
