What is archive in Postgres?
Archiving WALs. As you keep modifying the data in the databases on a server, WAL files keep getting generated (and discarded after a while). In PostgreSQL terms, copying out generated WAL files is called archiving, and getting the server to read in a WAL file and apply it is called restoring.

What is the difference between bartender and barman?
To be honest, there’s no difference between the terms “barman” and “bartender”. They mean exactly the same thing.
How does barman work?

Bartenders have to know a wide range of drink recipes and be able to mix drinks accurately, quickly, and without waste.

What happens if PostgreSQL file system fills up?
(If the file system containing pg_xlog/ fills up, PostgreSQL will do a PANIC shutdown. No committed transactions will be lost, but the database will remain offline until you free some space.) The speed of the archiving command is unimportant as long as it can keep up with the average rate at which your server generates WAL data.
Where is Postgres archive _ command parameter set in Bart?
