Re: pg_dumpall: could not connect to database "template1": FATAL:

Hi,

now I have another problem. Sorry I am an absolute beginner.
When I restore the dumpall backup with

"psql -f infile postgres"

I get lot of errors > "already exists" and the database is not restored to the point of the backup.
I mean after I made the backup I changed something and I expected that this change is undone after I restore the backup which did not happen. Looks for me like nothing was restored … ?

Thank you for your help.

Regards,
Robert
