Hi list,
I am happy to announce the new release of pg_idx_advisor version 0.1.2.
This is a PostgreSQL extension which allows a user to get index advice from
the DB optimizer.
It's the first "stable" release so please don't go running this on your
production environment :)
But, I'd greatly apprecia
Hi,
I'd recommend looking into 2 solutions here, depending if you want to keep
the data or not and how "fault tolerant" is the app (could you loose data
from the last hour?)
If you could loose some data and you don't intend keeping the whole data
set - I'd look at using RAM as your storage - it's t
Hi,
effective_cache_size is used only for query planing - you will not see it
in vmstat etc.
the default is 128mb, meaning you'd expect to see major differences when
running with 128mb vs 80GB of effective cache.
I'd take a look at your execution plans - I think you would find them very
different
Hi Aviel,
you can use the 'show cluster' command to see the repmgr state before you
do the 2nd failover - make sure the node1 is indeed marked as replica.
After a failover the Master doesn't automatically attach to the new master
- you need to point him as a slave (standby follow - if possible...)
Hi,
The clone command just clones the data from node2 to node1, you need to
also register it with the `force` option to override the old record. (as if
you're building a new replica node...)

Hi,
You can do this today using inheritance.
define a table "tagable" with person & blog as child tables.
than you could run queries like:
select * from tags JOIN tagable on (tag_id = tag_fk);
tag_id | tag_desc | id | tag_fk | data

Hi, Don't know if it's exactly what you're looking for but the MADLib
package has utility function for matrix and vector operations.

Hi David,
How many different table/objects do you read from and do you use bind
variables?
Each postmaster process keeps internal dictionary on objects and queries
ran - If you have too many objects or queries planned you might take up too
much ram.
If this is indeed your situation, you might bene
