We tried pg_dump write to a pipe with compressed format and faced issue as in thread referred here.

The complete command line was?

It was on windows client and for postgres 9.2 version. So during pg_restore, seek error was seen. With pg_dump writing the dump to a file and then move to another machine for backup, this problem was not there.

The pg_dump command used for this was?

But now the issue is that we need to have a  lot of free space to write the dump file
Size of file?

So trying to understand if the compressed format still needs the staging of output file with the latest versions? Or we can write the output to a pipe to move the data to another machine for backup.

What happens if you don't compress the pg_dump output?

In other words is the network fast enough to compensate for not compressing?


Regards,

Meera
