7.3.2 Regression Failures Worth Looking Into

NetBSD 1.6 / Alpha (64-bit)
Postgresql 7.3.2 & 7.4-dev

I compiled 7.4-dev and had success with all regression tests. However when
I went back to 7.3.2, about 15 out of 89 tests failed.

Failed how? Without looking at the diffs, it's impossible to evaluate
the seriousness of the issue.

I'll be using 7.4-dev, but I'm wondering if it's worth it to the
Postgresql community if I dig further to see why those tests failed;
considering that obviously 7.4-dev fixed all of them.

AFAIK there are not any portability enhancements in 7.4 that might
explain such a difference. So the 7.3 results are interesting. You
should probably rule out pilot error though (does "select version()"
confirm that you rebuilt with the newer compiler?)

I can send the diffs to you Tom, but it's too big to send to the list.
Would that be ok with you?
