I need some clarification on how to monitor BDR nodes. In particular
determining replication lag. As an example, I have a two node cluster with
nodes ‘A’ and ‘B’.I need to be able to look at node ‘B’ and determine if it
is lagging behind node ‘A’, by interrogating node ‘B’ only.

I am trying to determine the behavior of a system using ZFS to back a
PostgreSQL instance as it relates to fillfactor and table clustering.
ZFS implements copy-on-write, so when PostgreSQL modifies a block on disk,
the filesystem writes a new block rather than updating the existing block.

Even with COW, I can see fillfactor 100% still have its virtues. For

Hi,
After upgrading our database from 9.3.5 to 9.4.1 last night, the server
suffers from high CPU spikes. During these spikes, there are a lot of
these messages in the logs:
process X still waiting for ExclusiveLock on extension of relation
Y of database Z after 1036.234 ms

Well it is an upgrade from one major version to another, so you have the

I have one newbie question which I hope one kind soul of this list can help

The situation is that I have two postgresql servers:

populated with data,
-9.3 running on Ubuntu 14.04.02 with no database created

Yes. Use the pg_dump from the later postgres, which can read old
versions and generate any output needed for the new version.

Hi Adrian,
I didn't received any answer from Andrews.
Yes, sorry I didn't describe completely my migration plan.
Right now the database 'db' is in NAS1 mounted via nfs with computer 1

I want to migrate 'db' to a faster NAS2 mounted via nfs with computer 2
