Hello!
Due to speed up loading of a table of about 4 fields with 10 millions of
record, are there some parameters to optimize?
In same machine it takes about 15 minutes, in other machines about one hour.
Parallel mode is better than direct mode?
Other interesting things?
Thank you in advance

The streaming replication built into PostgreSQL would work fine for your
use case, assuming that you are OK with having only one primary supporting
writes and any slaves being read only as it currently (9.0-9.4) only
supports a single master. This will put minimal load on your primary server

Hi,
I am trying to setup partitions and as a test, I was able to follow the
example in the Postgres docs using the date as a condition.
Now I am trying to partition on a column with the data type character
varying. I want to partition based on an invoice ID consisting on letters
and numbers
I think the problem is you need to specify NEW.invoice in all comparisons
(don't quote the 'column')and always, Always, ALWAYS end each statement
with a semicolon.
IE:
IF (NEW.invoice = 'I-1') THEN INSERT INTO myschema.mywork VALUES
(NEW.*)
ELSE IF (NEW.invoice = 'I-10001' AND NEW.invoice =

What you suggest is a new column type, and that would be something that
needs to be reviewed and implemented by the PostgreSQL developers. Since it
is not a SQL standard, I doubt it has much chance of implementation. That
being said, you should understand that all triggers require the need for an

Thank for for the valuable feedback everyone. Much appreciated.
As I look at the Jabber install doc they say to use 9.1.1(which I am hoping
means 9.1.X (15) at least). I am afraid they may not be supported otherwise.
