Tom;
IT WORKED! This is what I did:
env | grep CFLAGS
and that produced all those flags as you predicted (-O9 -funroll-loops
-ffast-math -malign-double -mcpu=pentiumpro -march=pentiumpro)
unset CFLAGS
make clean
./configure --enable-odbc
make
make install
a subsequent pg_dump of the staging system's database produced NO ":60"
substrings in any time stamps!
Thanks much for your help!
Martin
p.s. interesting to note -- my dev box is actually the same distro
(slackware 8.1) but running in a vmware window. there was no such CFLAGS
env variable set and pg_dumps on the dev box are ok. the distro install
must set the CFLAGS based on hardware (the laptop is a Compaq PIII/700,
and the staging box is a P4/1.7G on an intel chipset board). Anyway,
really happy this worked -- thanks again. Let me know if there's anything
I can do.
