Bug#839131: RM: pgespresso -- ROM; pgespresso is not neded anymore with Postgres 9.6

[Marco Nenciarini]

Package: ftp.debian.org
Severity: normal

PostgreSQL 9.6 has been released today. It includes a new backup API that 
supersedes the pgespresso one.
Barman 2.0 already knows it and will use the 9.6 backup API.
