I'm a new user of postgreSQL

I was loking at the documentation and testing some
things and I make:

select * from pg_stat_database;

pg_stat_database is writen on the table of page 317,
one os the outputs is numbackends that is the number
of
active backend server processes. I would like to know
what is a active backend server processes.

Tank very much

In PostgreSQL every connection spawns a new backend that operates on the
database semi-independently, cooperating with the other backends by
means of shared memory.
