ERROR column n_mod_since_analyze does not exist

[schurikov]

Hi!

I've installed the latest available version of your plugin to monitor my PostgreSQL 9.2.24 on CentOS7, everything works fine except the error below:

14490:20180913:093905.765 PostgreSQL: PostgreSQL error for query "SELECT SUM(n_mod_since_analyze::bigint) FROM pg_stat_all_tables WHERE schemaname <> 'pg_catalog' AND schemaname <> 'information_schema' AND schemaname !~ '^pg_toast'": ERROR: column "n_mod_since_analyze" does not exist LINE 1: SELECT SUM(n_mod_since_analyze::bigint) FROM pg_stat_all_tab...

How I can fix this error?

With best regards
Sergey
