pgsql: Add memory info to getrusage output

Add memory info to getrusage output

Add the maxrss field to the getrusage output (log_*_stats). This was
previously omitted because of portability concerns, but we feel this
might not be a concern anymore.

based on patch by Justin Pryzby <pryzby@telsasoft.com>
