I ran uncompressed pg_dump on multiple TB+ sized databases from v8.4 servers
across the LAN using 9.6 binaries on the remote server. It was quite fast.
Threading was key.
According to the manual: https://www.postgresql.org/docs/12/app-pgdump.html
<https://www.postgresql.org/docs/12/app-pgdump.html>
the "directory format" is the only format which supports parallel dumps, if
I'm not reading it wrong.
How did threading solve "between database" dump/restore for you? Did you dump
to "directory format" first, then restore? If so, then that requires quite a
bit of temp-space...
