Re: [GENERAL] Realtime Query Dashboard Results
On Fri, Jan 7, 2011 at 5:21 PM, Oliver Kohll - Mailing Lists oliver.li...@gtwm.co.uk wrote: Charts are updated once a day overnight, or cached whenever someone looks at them in the system underlying the dashboard, so they are at most one day old. A chart is also updated when a user clicks on it to drill down to the data. Of course what you decide depends on what the business use case is and what demands there are on the system. In my cases so far the slowest charts take 1 or 2 seconds to generate by SQL so if necessary, each could be loaded in in real time over AJAX, though that hasn't been needed yet. We found for our use case that customers don't like 1 day old reports. We've moved much of our dashboard statistics to trigger-based materialized view, so whenever they reload, they get current numbers and the cost to compute those numbers has already been amortized over the metric-gazillion updates and inserts that comprise them. :) Computing them on-the-fly is just too time consuming and people don't like to wait, either.

[GENERAL] migrate hashname function from 8.1.x to 8.4
Hi all, I'm trying to upgrade our pgsql from 8.1 to 8.4, but our system's login uses the hashname() function in order to get the proper password validation. Now pgsql's 8.4 hashname function is not compatible with 8.1's function. Do you have any ideas how I can reproduce 8.1 function in 8.4? Thanks in advance for any help you can give me! Cheers, Nicolas.

[GENERAL] Using aclitem[] at application layer
Hello, In an attempt to implement ACLs at the application layer (for resources stored outside of the database), I am evaluating using aclitem[] as a column type. All the functions I would need seem to be in place: aclcontains, aclexplode, aclinsert, aclitemeq, aclitemin, aclitemout, aclremove, but they are conspicuously missing from the documentation (http://www.mail-archive.com/pgsql-patches@postgresql.org/msg03400.html), so I wonder if there are any caveats or hurdles which would make me consider writing my own type. From a cursory examination, it looks like the limitations would be: 1) roles must refer to postgresql roles (that's fine for my case) 2) permission options are hardcoded to arwdDxtXUCTc (not so great) Are there any other problems I would encounter?

Other than the fact that we'd feel free to change the behavior of any or all of that with no notice? aclitem is an internal type. If you depend on its behavior, you'll have only yourself to blame if your application fails in the future.

Re: [GENERAL] migrate hashname function from 8.1.x to 8.4
Hi Craig,
Thank you for your reply!
well, what i mean is that hashname() function would return a different value
depending the pgsql version.
Consider this query (note that i'm using some extra implicit cast functions
here):
SELECT password FROM user WHERE password = hashname('AZALEA')
UNION ALL
SELECT hashname('AZALEA')::text;
in 8.1.x it returns:
-588380923
-588380923
whereas in 8.4 this query only returns:
-10546138
And tweaking the query to show the difference more clearly:
SELECT password FROM user WHERE login = 'SIST'
UNION ALL
SELECT hashname('AZALEA')::text;
this returns:
-588380923
-10546138
Am I missing something?
Just a side note: our goal with this upgrade is to improve our system's
performance
and stability (which 8.1 is not) while not embarking in any kind of refactoring,
as plans are underway to develop a new system. what we are looking for is
just a quick fix, if there's such thing out there!
Any thoughts?

[GENERAL] database is growing... 1GB per day basis
Hello, my name is raghu. I work for Avaya. We uses postgres as database in our application. Our application is a jboss based enterprise application, that does some updates operations based on requests from client. We use entities and hibernate for data access within our application. I have couple of questions, as listed: 1. We observe that database is growing very fast - many sets of files with size more than 1 GB. Please see some sample snippets of the file lists: This does not happen regular basis. However, we have a few instances of this incidence, and pretty much blocked on this. What could be causing this? What can be done to diagnose/ resolve this issue? We are running out of disk space in our box quite quickly due to this issue. Any thoughts please? 2. One of our table has columns for LOB. All other tables are of primary types (there are a few sting/ varchar types as well). I understand that postgres maintains large data objects in pg_largeobject. Is there a way to find the data within those table? How can I find out the corresponding table information or row corresponding to this large data maintained/ managed in pg_largeobject? I also hear about pg_toast... wot is the relation between pg_toast and pg_largeobject? I would appreciate your early response and help very much! thanks/ regards, raghu
