Re: Monitoring Replication - Postgres 9.2

Yep.. once a minute or so. And yes, I need to store a history with timestamp.

Any idea? :)

so create a table with a timestamptz, plus all the fields you want, have a script (perl?  python?  whatever your favorite poison is with database access) that once a minute executes those two queries (you'll need two database connections since only the slave knows how far behind it is), and inserts the data into your table.
