Small patch for pgstat.c: fix comment + pgindent - Mailing list pgsql-hackers

Hello

I noticed:

http://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=b6fb6471f6afaf649e52f38269fd8c5c60647669

... that comments for procedures pgstat_progress_update_param and
pgstat_progress_end_command are identical. Here is a patch that fixes
this. Also one empty line added after running pgindent on this file.

Best regards,
Aleksander
