Hm, it sounds like I guessed wrong about which version was newer ... is
there something flaky about your machine's system clock?  The file
timestamps in the two tarballs definitely pointed the other way.

Nope, not a system clock problem, not that I know of... I don't know what the problem was... anyway, with the patch I made it should now be fully functional.

Yeah, your to/from text functions simply did not work --- the VARDATA
hack for example presumes that the data part of a text value is
null-terminated, which it isn't.  In any case it seems pretty likely
that the content of TEXT datums will change someday to allow better
charset/collation support, so you really are better off calling
textin/textout if possible rather than assuming you know the
representation of type TEXT.  I copied the GET_STR/GET_TEXT macros
from some other contrib module ... you're free to do it differently
if you want, but in any case you have to deal with the fact that TEXT
is *not* a C-string.

Yeah, that's what I painfully learned, specially with the *_cast_to_text() functions... those were definitely crashing the server. I didn't know the VARDATA() "hack" could fail at some point (even in the patch, I already replaced it with GET_STR(), just in case)... and since it took me so long to figure out why the other two functions where crashing, and not knowing what exactly was that you made with the GET_TEXT() macro, I just decided to use my own patched version... I suppose the use of GET_TEXT() is better, as it's smaller and makes the code easier to follow; perhaps we might want to change those two functions back the way you had them (using GET_TEXT())

As for the log message changes, there's room for debate about that, but
the way you had it struck me as far too chatty.  The use-case for weak
checking is that you have a large pile of data you don't want to
validate right now, correct?  So why would you want a warning for every
single bad datum during the import?  Also, all the fancy formatting in
that one big warning was directly against our message style guidelines.

That's right, that's the idea behind "weak mode"... I've been in that position and I found the weak mode very useful, so I thought it would be nice to have it as a feature that others could benefit from. And yes, I know the messages were far too chatty, as you rightfully said so. In my latest version (before the patch) I took away some of the messages, and I also shortened the *big* warning to a single lineĀ… but I think not having so many messages it's truly better; I wasn't sure when the messages were shown (this is my first module, you know) but it seems those removed messages were really not needed at all.

I'm very happy to have contributed a bit to the growth and improvement of PostgreSQL, and I look forward the day I can make bigger/better contributions. And Tom, were you able to apply the patch without problems ('cause this is one of the first times I post a patch in a mailing list.)
