The smallest backup would be a compressed custom format "pg_dump":
pg_dump -F c -Z 9 ...
I is very unusual for a custom format dump

Hello,
Postgres version : 9.6

We are working on HA setup for postgres cluster of two nodes in
active-passive mode.
Installed:
Pacemaker 1.1.19
Corosync 2.4.3
The pacemaker agent with this installation doesn't support automatic
failback. What I mean by that is explained below:

Hi all.
PostgeewSQL 11.4 on Centos 7.
I created a test bed on VirtualBox and test HA cluster by random failures in
loop. Sometime, in case of longest switching from failure, I get strange
behaviour. The walreceiver is stopped by timeout, but don't restarted for 2
hours. May be I agree with sto

Hi,
macos-10.11.6
postgresql-9.5.16 (server)
postgresql-9.6.12 (client)
I've just rebooted my macos laptop for the first time in months
and have started having a problem loading database backups there.
I get this error output:

Yes, t
Thanks Laurenz Albe for reply.
Unfortunately this index is only frequently used during a certain period of
time(such as 9:30am - 12:00am) .I usually encounter slow load of this index
during some other time.
Then it seems to me the only answer for this case would be the pgprewarm and
pg_cron ?
