[check_postgres] Adding a Dead Rows check

[Josh Berkus]

Folks,

I'm trying to add a check for dead rows (based on pg_stat_user_tables)
to check_postgres.  This would be useful as a second, and more accurate,
bloat check, at least for tables.

However, I'm having trouble pinning down all of the places I need to add
code for a new check.  Is this documented somewhere?
