By definition, UNION does a DISTINCT. In fact, this is going to hurt you; you'll end up doing 4 distinct operations (one for each SELECT DISTINCT and one for the overall UNION). Unless some of those tables have a lot of duplicated location values, you should either use UNION ALLs or drop the DISTINCTs. Note that going with DISTINCTs is different than what your original query does. You should also consider this: SELECT name, id FROM locations l WHERE EXISTS (SELECT * FROM pa p WHERE p.location=l.id) OR EXISTS (SELECT * FROM andu a WHERE a.location=l.id) OR EXISTS (SELECT * FROM idu i WHERE i.location=l.id) This query would definately be helped by having indexes on (pa|andu|idu).location.

Trying to create a teable fails This results from script logging backspaces into the log file instead of deleting characters in there and my not spotting that when cleaning up the log file. Nothing to do with the question at hand. It doesn't matter in this particular case because we could see what was intended (I honestly wondered if that was a typo that 7.1.3 accepted), but sometimes subtle differences can matter so it's better to post code that others can copy and paste verbatim into their database -- that way the corrections themselves don't introduce different behavior. select f, f::timestamp at time zone 'MEZ' from test; f | timezone ---+ 2005-04-24 22:25:51.669218+00 | 2005-04-24 23:25:51.669218 (1 row) Huh ? This IS different time zones from the same timestamp within the same query, isn't it ?? No, it isn't. In the above example from 7.2.7 the second column has no time zone specification whatsoever; if you cast it to timestamp with time zone then you get the following: select f, (f::timestamp at time zone 'MEZ')::timestamptz from test; f | timezone ---+--- 2005-04-24 22:25:51.669218+00 | 2005-04-24 23:25:51.669218+00 (1 row) There's only one time zone displayed here: +00. Those are different times being displayed in the same time zone, not the same time being displayed in different time zones. Other versions of PostgreSQL give varying output, but they all show both columns in the same time zone. The problem I was discussing involves getting *different* time zone specifictions in the output. That is, something like this (which apparently is possible in 7.1.3 but not in later versions): f | timezone ---+--- 2005-04-24 22:25:51.669218+00 | 2005-04-24 23:25:51.669218+01 The fact that different versions of PostgreSQL get it right or wrong in a variety of ways indicates that the logic may need to be fixed but does show that in principle it is quite possible. Certainly it's possible in principle; the question is how to do it in practice in modern versions of PostgreSQL. As far as I can tell it's not possible (short of changing the type to text, as one of my earlier examples did), but again, I'd be pleased to be corrected (preferably with an example that works in 8.0.2).

Re: [GENERAL] UltraSPARC versus AMD
I am looking at options for a customer with an installed base of ~5000 Sun workstations running 400-500MHz UltraSPARCs. They're not getting the performance they need. They shipped me two Tadpole Bullfrog machines, a Bullfrog I and a Bullfrog II for evaluation. http://www.tadpole.com 1.28GHz single or dual CPU UltraSPARCs. On board SCSI, but they installed IDE drives instead. In my *utter* lack of enthusiasm over this option, I was gathering ammunition for better hardware. I went to spec.org for speed comparisons, and sun.com for price comparisons. Sun's *entry* level servers are more powerful when running AMD CPUs. I note with interest and appreciation comments about the bigger iron from Sun and IBM. That's not what I'm in the market for, but good info as always. My evaluation is that a single or dual core AMD 64 Athlon in a rugged laptop is going to give a performance enhancement (SPECMark wise) of about an order of magnitude over their current hardware base. And it's cheaper. The current hardware base contains a 10k SCSI Fast Wide Ultra single disk on a 440MHz CPU as well as a 7200 IDE on a 500MHz CPU. The SCSI with the slower CPU runs the application 8% faster. Obviously I'll need to work on the proper I/O subsystem because that's apparently more of a limiter than the CPU speed.

[GENERAL] installation as service failed on windows xp
Hi, The first time I install postgresql in Windows XP, I install it as service. The installer asked me to create postgres account. Ok, fine... then someday I uninstalled postgresql so I can install the newer version of postgresql. But first to make it clean, I delete the postgres account from right clicking the My Computer, then click the properties. Choose the advanced tab, then click the user profiles setting buttons. Then when I try to install as service with postgres account, it said : Invalid user name specified: Logon failure: unknown user name or bad password. I try to create postgres account from start menu --- account or control panel -- user account, it said that The account already exists. But there is no postgres account in User Accounts window. So the questions is: 1. How do I really delete the postgres account that created by postgresql installer??? Thank you.

[GENERAL] pgexplorer adm
I went to http://www.pgexplorer.com and downloaded their adm program for postgresql running on windows. The site proclaims that it is now FREE, yet there is a moment of confusion when you go to install and it talks about 30 evaluation period. Yet, once you install, if you click on the REGISTER button, it tells you that this is a FREE copy. Installed and ran with no effort on my part. I think I shall try this out for a while. I have yet to get Toad to run because I cant figure out what it wants me to fill in in the odbc dsn setup for datasource and location. But I imagine that pgexplorer.com will work ok for now. But thanks everyone for your suggestions. I am still shopping around for a language to use for front end. I suppose that Access will do a lot for me. I feel very comfortable with Liberty Basic, but it does not offer any easy way to do odbcconnections. I am looking at Truebasic and Powerbasic. I really wish that there were some knd of easy to use IDE window painter like Powerbuilder used to be. But, I guess if I use MSAccess, and VBA, then I shall be learning some useful skills. I realize the virtues of Delphi, but I just dont feel like attempting it at this stage of the game. But, at least, each week, I am making a little more progress, and learning some interesting things. Is there some kind of drag and drop Java ide painter which would be fairly straight forward, without having to become an expert in Java, just curious. I know nothing about Java. I tried out a free Cincom Smalltalk, which has a nice tutorial, but I have not seen a tutorial which walks you through doing a menu and windows for a SQL application.
[GENERAL] pgadminIII - creating servers
I just now tried creating a second server with pgadminIII. I am confused as to why one would have more than one server. There does not seem to be any way to "switch" from one server to another, or to log into one particular server (and not the other), or to create tables specifically for one server. I find the concept rather confusing. I understand that if I limit myself to one server, then I may define different database, and log to a particular database, and see only the tables in that database. Any explanation regarding more than one server will be appreciated. Thanks.

Re: [GENERAL] Migrating MySQL app to postgres?
Hi Rich, Guess now's the time. I'm trying to find a copy of pygresql to use, but it's not easy (www.pygresql.org leads to druid.net and there's nothing on the page about pygresql). I'm learning python to use on a major project here (but the core libraries will remain in C) so I'd like to use that for the UI on this project, too. I'm still not sure about the reports, but one step at a time. That is, will the pygresql display nicely formatted reports based on sql queries to the backend? Need to find out. I have found using python with reportlab (http://www.reportlab.org/rl_toolkit.html) very easy to create pdf reports based on queries. Hope this helps, Joe ---(end of broadcast)--- TIP 7: don't forget to increase your free space map settings

The docs say that GB18030 is supported as a client-side encoding only. So pick any superset encoding (UTF8 maybe?) as the database encoding, and then set client_encoding to GB18030. regards, tom lane ---(end of broadcast)--- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
