In fact, I tried fist my own mysql sdb driver. but it constantly crashes.

I then tried the pgsqldb.c sample provided *as is* and got the same 
crashes.

I tried this code on LinuxPPC 2000, on YellowDog PPC 1.2.1, and on RedHat
6.2 on Pentium, and got the same results.

since you have the same problem, I sincerely believe now there's a bug
in the generic sdb driver...

btw, thanks for the recursion trick. my NS doesn't recurse (:
