Hi All,
Recently we got into problem of giving permission
to data directory.
(1) Actually we are doing project on PostgreSQL in
group of two. We installed individual copy of PostgreSQL into our group
directory.
(2) When I created data directory and ran "initdb"
it makes me( takes my login

Hi,
someone asks me about an utility to check any PostgreSQL database
data to be sure that:
1) there is not any page corrupted
(by a memory fault or a damaged disk)
2) re-check any constraint inserted into the database
I really don't know if PostgreSQL itself has any crc check on
its pages.
2) re-check any constraint inserted into the database
There should not be any if it was accepted, however if it's a new
constraint it doesn't get applied to data that already exists. A dump
and restore will ignore these as well (with good reason).
I suppose the easiest way to find if data
It doesn't really say, however, it makes me wonder if it's SGI's KAIO
(http://oss.sgi.com/projects/kaio/) effort which is reported to provide
up to 35% performance improvement for heavily I/O bound applications.
Again, I'm not sure it is SGI's effort that is being talked about here,
nonetheless,

We've seen several reports now of 7.2 postmasters failing to start

a loopback UDP port on 127.0.0.1, 7.2 will exit with

It occurs to me that a more friendly behavior would

You'd be reporting elog(ERROR) in any case.

Au contraire, it is not assuming anything. It is

Cool. Thanks for the information. The only other PAIO effort that I
knew of was the glibc user space effort...

Hi all,
In IRC, StuckMojo commented that the following behavior doesn't seem
to be ideal:
nconway= create table my_table (col1 int default 5, col2 int default
10);
CREATE
nconway= create view my_view (col1, col2) as select * from my_table;
CREATE
nconway= create rule insert_rule as on insert to

In other words, when the insert statement on the view is transformed by
the rule, the default value columns are replaced by explicit NULL
values (which is the default value for the columns of the pseudo-table
created by CREATE VIEW). Is this the correct

However, it does appear that we can tweak flex for more performance
(usually at the expense of a larger generated parser). In particular, it
looks like we could use -Cf or -CF. Is this a good idea?
Probably. Run some performance tests if you like. It looks like -CFea
BTW. There are good reasons sometimes for having data that violates
current constraints. The top of a tree may have a static record with
a null parent. The NOT NULL constraint added after this entry (via
alter table add constraint) should not affect the static record, so
