PGAdmin 4 fails to backup database with no errors

问题

I try to backup my university project database. I followed the instruction, everything seems to be inputed:

1:

2:

3:

But the only pop-out I get is this one in right-bottom corner of PGAdmin 4:

From the Official site, there should be another pop-up message, similiard to this one:

But I don't get this one, nor I get the other one that is displayed where any error occurs.

I tried to directly use pg_dump.exe, but it prompts me for a password. I tried all my passwords - user password, server password which I use to connect to my database in PGAdmin 4, other passwords, but none of them seem to work.

I tried to find any information about this, but all articles about pg_dump.exe are about how to automatize password input. What is the cause of this backup silent failure, and which password does pg_dump.exe need?

I'll add any details if needed, I was trying to figure it out for 4 hours now...

回答1:

Can you upgrade your pgAdmin4 with version 1.2 and try again? https://www.pgadmin.org/

I think they have fixed the issue in new release.

I've tried with pgAdmin4 1.4 and still my backup file was empty so I moved back to pgAdmin3 and it worked like a charm. Although pgAdmin3 is not maintained anymore I suggest you use it until pgAdmin4 is up to it but right now it is way too slow.
