Thanks everyone for your valuable inputs
(Before I answer: WHY?)Not intrinsically. You might be able to play weird games with ssh tunneling, but then I'd say "find a different solution to your problem."On Sun, Jul 28, 2024 at 11:13 PM Zaid Shabbir <zaidshabbir@gmail.com> wrote:Hello,One relevant question..Is there any way to Stream pg_dumpall directly from single CentOS7 to Multiple RHEL server directly through a single command ?On Mon, Jul 29, 2024 at 7:12 AM Tom Lane <tgl@sss.pgh.pa.us> wrote:Brock Henry <brock.henry@gmail.com> writes: > I personally would create an ssh tunnel for port 5432, if ssh was open but > 5432 was not. +1, but I think your example is not quite right: > ssh -L 5432:localhost:5432 redhat_ip_address > pg_dumpall -U postgres | psql -h localhost -U postgres If you have a local PG server, it's probably using 5432 so that ssh can't bind to that.
