I have noticed that in documentation for PG versions before 11devel some
*pg_stat_replication/* /links refer to *collected statistic views* table
instead of itself definition. Fixes for version 10.2 are gathered in
fix_pg_stat_replication_links_doc.patch

This was due to a reorganization of the documentation in 9.5, so the
links became outdated. Fixed.

Also I am confused by the definition of *checkpoint_warning* parameter,
namely the phrase "caused by the filling of checkpoint segment files". I
think the word "checkpoint" is unnecessary here. I tried to rephrase
this definition in fix_checkpoint_warning_definition_doc.patch.

This was more appropriate when the related parameter was called
checkpoint_segments, but now it indeed seems confusing. Also fixed.
