Lintian errors fixes

Guys,

Here is a quick fix of the following Lintian errors:
Now running lintian...
W: pgbadger: manpage-has-bad-whatis-entry usr/share/man/man1/pgbadger.1.gz
W: pgbadger: manpage-section-mismatch usr/share/man/man1/pgbadger.1.gz:127 1 != 1p
Finished running lintian.

Can you please merge this branch?

Regards,
