pgsql: Change debug printing to log filename

Change debug printing to log filename

When restarting the cluster fails the code introduced in 33774978c78
printed the full log contents to aid debugging.  For cases when the
logfile is large this adds unnecessary overhead.  Reduce to printing
the logfile path instead.
