Todo Dump

Changer le schema de nextcloud (ne pas laisser dans public)
Ne dumper que le schema nextcloud
Dumper le schema au format text et les data au format custom ?
Changer le tar : faire un cd avant le tar pour ne pas archiver les chemins absolus

set search_path to public,nextcloud;
alter schema public rename to nextcloud;
create schema public;
alter role nextcloud set search_path to nextcloud;

pg_dump --username=nextcloud_backup -d nextcloud -h localhost --schema-only -n nextcloud | gzip > $BACKUP_DIR/schema-nextcloud-dump.psql.gz
pg_dump --username=nextcloud_backup -d nextcloud -h localhost --data-only -n nextcloud -Fc > $BACKUP_DIR/data-nextcloud-dump.custom
