Re: [GENERAL] Tracking SQLs that update data
It's far easier to adjust the logging. psql mydb alter mydb set log_statement='mod'; Thanks Scott. Two questions: 1. Will this log_statement='mod' be a permanent thing, or when I have done my testing and identifying the problem SQL, I can set it back to default so not too much logging is being done? 2. After this statement, how or where do I find the culprit SQL?

Re: [GENERAL] [Blatant Alias Abuse] Anyone want to help out with a coding problem?
I am not anti-DotNet.. i wanted to make sure everyone understands the pitfalls one encounters when writing code for a OS and .Net-version specific framework specifically: 1)change OS - code doesnt work 2)change supported .NET framework version - code doesnt work if you're writing missile-guidance systems that only work for one specific suite of OS -compiler-environment thats perfectly ok..in fact you specifically dont want portable code it has been my experience that non-portable code is generally 1)easy to code upfront..usually a day or two 2)a nightmare to maintain..as you'll have to rewrite what you have for each OS and .NET-framework permutation you encounter so to lure customers in go for the quick fix onetime solution. then when they needs conversions ..quote them big $ conversion the latest Mono implementation i have is horribly gacked..do you have connections at novell that have a working copy?

From: m...@kitchenpc.com To: mgai...@hotmail.com CC: pgsql-general@postgresql.org Regarding the RAM thing, all the recipes will be in the database but when the engine loads, it will create a graph in memory of all the recipes. They'll actually be linked by similarity, recipe A will have an array of pointers to other recipes that someone who likes recipe A might also like. Though this design may be rethought if it doesn't work out. The data in RAM is read-only and will be updated with fresh DB data once every day or so. The reason I need to keep the data in RAM is I need to be able to very quickly walk this graph and a relational DB doesn't really fit for this. I've done some testing and if I store about 100,000 recipes in memory, it's only a few hundred megs of RAM. This is nothing for a web server, and even if I need more, this facility could be moved over to a dedicated server that the main website just queues up requests on. Regarding Mono, I'm not sure it's a wreck. It's come a long way and several sites use it in production. However, I'm keeping my code runnable on both .NET/Windows and Mono/Apache because I haven't yet reached any definitive conclusions on what it will be run on. My code is 100% managed, there are no native DLLs as you mention. I've actually ported my site over to Mono as a proof of concept and it took one evening, not 6 mon. I don't really think your rant on MS/.NET is really warranted here. To each is own, if you're a Java guy then that's fantastic. I'm not much into it and prefer C#, especially since I have 10 years of experience with it and zero with Java. I'm well aware of the requirements of .NET, Mono, Apache, etc. Thanks for your feedback.

[GENERAL] Inserting additional data into pg_statistics
Hello everyone,
I'm new here, but I have a problem and couldn't find a solution so I
hope you will help me.
I'm trying to reproduce the pg_statistics catalog from one database
server to another one. To retrieve the data from the first server was a
trivial job. The trouble was when I tryied to insert new record to
pg_statistic table on the second server.
To be more precise, I want to run this [0] query and I'm struggling with
this error [1]. The query is generated by pg_dump. Anyways, it will be
the same problem if I write the SQL statement by hand.
So, has anyone any ideas how can I insert new record to pg_statistics
system catalog ?
[0] INSERT INTO pg_statistic
VALUES (
54655,1,0,26,-1,2,3,0,0,1058,1058,0,0,null,'{1}',null,null,'{AFRICA
,AMERICA}',null,null,null );
[1] SQL error:
ERROR: cannot accept a value of type anyarray
Thank you a lot.
Looking forward for your replies.

What are the real advantages of creating a VPN, if you have already set your server like this for example: hostall all zzz.zzz.zzz.zzz/32 md5 I mean, don't you already have an md5 encrypted channel between the server and zzz.zzz.zzz.zzz ?

Re: [GENERAL] Inserting additional data into pg_statistics
Thank you for your reply, Tom. Why I can't ? And for my purpose is not a bad idea. I mean, I have to do this and somehow I should find a solution. In order to use ANALYZE I need the same data on 2nd machine, but the data is quite large and the only information I need are the statistics from pg_statistic. So, why I receive that ERROR and I run the INSERT statement ? Can anyone tell me where to look into Postgresql source to see how the engine updates this table ? Looking forward for reply.

[GENERAL] A thought about other open source projects
I happened across (yet) another open source project which supports MySql and Derby (its a Java app) and is thinking about supporting Oracle (they have actually bought a licence) but does not support Postgresql. This particular project is onehippo.org, but there are many others. Another perhaps more important project is the Akonadi project in KDE, which is only gradually getting around to Postgresql. These projects need help to realise that adding Postgresql is not a big job, especially for those using JDBC which can already connect to all DBs. It strikes me that if the project could write a few pages gleaned from other porting operations, then whenever a project like this is found they can be pointed to these pages and shown how easy it is to do. Then if someone spots a project that might use Postgresql they can simply point them at the pages.

Npgsql supports multiple resultsets. You can pass a query separated by semicolon ';' or you can use a procedure call which return a setof refcursor. On both ways, you will need to call NextResult in your Datareader just like with SQLServer. You can check our user manual: http://manual.npgsql.org to get more info about how to use refcursors I hope it helps. Please, let me know if you need more info.

For this reason, I use the LIMIT 30 OFFSET x clause on the select statement. However, I also want to know the total rows that match this query had there been no limit, that way I can display to the user the total count and the number of pages, and have Next/Prev buttons in my UI. I can think of the following ways to do this: 1) When the page loads, execute two totally separate queries. One that does the COUNT, and then another query immediately after to get the desired page of data. I don't like this as much because the two queries will execute in separate transactions and it'd be nice if I could just perform a single SQL query and get all this information at once. However, I will use this if there's no other way. Just run them in one transaction. You can also just show the Next/Prev buttons and then do something just for the case where there is no data. Or use LIMIT 31 so you always know that there is the next page with at least one record. regards Szymon Guz -- Regards, Francisco Figueiredo Jr. Npgsql Lead Developer http://www.npgsql.org http://fxjr.blogspot.com http://twitter.com/franciscojunior -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
