Thanks for your reply Martijn. I do not know for certain that its in pg_dump format, not having dealt with it specificly before. I will examine the files more closely to look for COPY statements. If not in that format, what else could it be that could be shoved right into a postgresql database?

Re: [GENERAL] How do i store arbitrary questions and answers in SQL?
I agree with Tim, that your option 3 is really not all that hard, and I suggest would provide you with the best solution. I'm assuming, however, that your application asks the question and checks the user supplied answer with the answer in the db (and not Jeopardy style). I might add a 'join' or 'answertype' field in the questions (qu) table to assist when drawing the application and to immediately know what table to verify the supplied answer against. Otherwise, I think you might need a query to check the type on the answer the user supplies and make a possible few passes (through the numeric and integer tables for example when the user's response is 42) - or some combination of outers to find the non null value field. For what it's worth, I'd probably also include a 'type' table to hold my application specific mask for the user's reply, and perhaps a attribute to hold the joining table name (I'm thinking about the future requirement to add a new type without much coding changes on the application side). So, now I'm interested in this, and I could see a use for something similar in the near future, I'll put the following out there for comment. Obviously I haven't put it into practice but perhaps it could work. One of differences from your original post is the absense of a serial field on the responses. I've only put a primary key which would link back to the the questions.qid field (so maybe it should be a fk? see my note about my pg newness in a moment). I'm assuming this is not a multiple choice type of situation. Each question has one answer (although not currently enforced in the db layer here since there is nothing stopping you from placing an answer in more than one of the response tables - I'm relatively new to pg and not sure of anyway to deal with this).

Dang. I re-read your post and see that you are not checking for the correct answer, you simply want to store the responses like a questionare. Well I still think a different table for each type of response would be beneficial, obviously, adding a serial field like you have done and the foreign key linking to the qid.

Re: [GENERAL] mising chunk
I had this problem a few weeks ago. What I did was isolate it into an individual row that was causing the problem, then going over the fields one by one, till I located the free text field that was responsible. Then I repopulated it with the value in the latest backup I could find. I wasnt able to find any better techniques on the web. For locating the faulty row, you might want to write a procedural routine that will query rows sequentially. I did it in a very crude way by using LIMIT statements till I hit the mark.

[GENERAL] Cutting the Gborg throat
Hello, I have been looking at the migration of Gborg lately. It looks like the only two active projects on that site are Slony, and pljava. Libpqxx has recently moved to their own Trac site. I would like to suggest the following course of action. 1. We set a read only date of 12/31/06 This means that all login capability, register capability, mailing lists, bug tracking, cvs etc... will be shut off. It will only be up for reference. 2. We set a shut down date of 03/31/07 This means it is down, rm -rf, whatever it takes. Why? Because past performance on the migration of gborg to pgfoundry has shown that it will not be done, regardless of who volunteers or who *thinks* they have time to do it. So what will this really take? 1. The respective project members need to register their projects with pgfoundry. 2. The respective project members need to migrate their tickets if they see fit. 3. The respective members need to register the email lists they want. 4. There needs to be communication between one project at a time to arrange a cut-over of their mailing lists. We have the ability to import mbox files into mailman so their mail archives will be preserved. Question: How is CVS handled on Gborg? Do they have their own repos? If so we can just move them to pgfoundry yes? Except for the pending screaming and yelling... is there really anything wrong with this? To cut a few things off at the pass: I think it is completely reasonable that we ask fellow community members to help in their own migration as this is a gratis service. I also think if those members were asked, they would be happy to help. I am willing to have Devrim and Darcy help with this. Sincerely, Joshua D.

Even if you've made yours readable, the default SELinux policy in FC5 prevents daemons such as the PG postmaster from accessing random parts of the filesystem. Consider using psql's \copy instead. regards, tom lane ---(end of broadcast)--- TIP 2: Don't 'kill -9' the postmaster
[GENERAL] jabber.postgresql.org is up
Hello, The community jabber server is now up. We are using the Wildfire server from Jive Software, backed to a PostgreSQL database (of course). Our current enabled features are: 1. Server side storage (for static groups etc..) -- We currently have a Slaves_to_WWW group for example 2. MUC (basically IRC for jabber) -- all muc conversations are logged to postgresql and in the long run will likely be searchable by members of the jabber service. 3. tls or ssl is required We do not support auto-registration at this time. -- The idea behind this server is to allow active project members to communicate without having to use public channels. We do not support communication with other jabber servers at this time. -- I don't really see a benefit to this at this time, but it is something that is easy to set up so it is a consideration in the future. If you are a project member (Gforge admin, Web team member, commiter etc...) please let me know if you would like an account. Sincerely, Joshua D.
