"[Errno 2] There is no such file or directory" when trying to backup the database in pgAdmin4

Question

Finally, I managed to bypass the control to manually set the "PostgreSQL binary path" in the settings (why did the user need to do this when it was not necessary in pgAdmin3?).

Although, frankly, I have no idea what I mean with the second field of the path called "Binary path of the extended EDB server." But I don’t get any more error messages due to this, so I assume it is ok to leave it empty.

Now I'm stuck in the next step.

When trying to backup the database, I need to enter the file name. No matter what I do here, I keep getting this error:

[Errno 2] No such file or directory

Well, it can't be that I have to create a file before pgAdmin is created, right?

What can i do wrong?

Answer 1

I just upgraded to pgAdmin v4.1 and this solved the problem :-) Thank you all for your help!

Answer 2

I solved the problem through the command line.

If we use the previous format, it has the same answer as yours:

$ pg_restore -d <DBNAME> --username=postgres g=<FILENAME> 
pg_restore: [archiver] could not open input file "g=<FILENAME>": No such file or directory

If we change the last parameter, it works correctly:

$ pg_restore -d <DBNAME> --username=postgres <FILENAME>

I assume the GUI command has changed in v4, but the pg_restore console is not working.
