What you have provided as information is not particularly helpful to
diagnose the problem.

What you need to do is to run one of the scripts in /tools/ for
testing system state:
  test_slony_state.pl
  test_slony_state-dbi.pl

(One uses Pg; the other uses DBI...)

Running them should give some better clue as to where the problem
lies.
