pgsql: Change default of log_directory to 'log'

Change default of log_directory to 'log'

The previous default 'pg_log' might have indicated by its "pg_" prefix
that it is an internal system directory. The new default is more in
line with the typical naming of directories with user-facing log files.
Together with the renaming of pg_clog and pg_xlog, this should clear up
that difference.
