How can I safely repair, knowing that I have the pg_dumpall of last night, but many dbs have changed today... ?
If pg_dumpall is your only backup mechanism then you've lost all changes after the dump was taken. You'll need to restore from that backup and then get pgbackrest (or another equivalent tool) up and running to protect yourself going forward
Mmm, there is some misunderstanding. I have lost nothing. All my DBs are ok. I am speaking of the specific "postgres" database that you connect to with \c postgres What is its use ? how to restore it ?
