What's the exact error message recorded in the postmaster log file?

The most likely bet is that the postmaster is failing to look in the
directory where the pg_stat_statements.so shared library is, which
would be a matter to take up with the Ubuntu packager(s) of Postgres:
postgresql-contrib really ought to be dropping its shared libraries
in a place where the postmaster's library search path will find them.
As a short-term workaround, I think it might work to put a full
path name into shared_preload_libraries instead of relying on the
code to find the library automatically.

But it could be something else.  The error message would help.
