Re: Normalization tools for postgres?

Please don't start a new thread by replying to another question.

If you are going to do that, please don't cross-post it in addition.
This doesn't appear to be anything to do with PHP.

I don't know of any tool that could do this automatically. Without
understanding what the columns *mean* how could it.

Well, given that the example just shows the author doesn't know what 1NF
means, I don't think it does do what you want.

I don't see any reason why the INSERTs won't work for PG just as well.

Can you state what problem you are trying to solve? Do people just email
you flat files and ask you to send them a relational database back? Is
there a specific file that gets imported on a regular basis?
