Обсуждение: 64 or 32 postgres

How to figure out whether the installed postgres version is 32 bit or 64bit ? We installed postgres801 from src on susu box with EMT64 bit hardware. I assume since the hardware was 64 bit, postgres should have compiled in 64 bit too, but then we ran into this error

FATAL: database files are incompatible with server
DETAIL: The database cluster was initialized without HAVE_INT64_TIMESTAMP but the server was compiled with HAVE_INT64_TIMESTAMP.

HINT: It looks like you need to recompile or initdb.

Any ideas ?

Thanks,

Stalin,

Probably the easiest way to figure out if the server is 64-bit is to
run 'file postmaster' binary.  However, the problem you are running into
is because postgresql was configured/compiled with

--enable-integer-datetimes  enable 64-bit integer date/time support

Recompile without this flag.

That has nothing to do with 64/32 bit; you changed the
--enable-integer-datetimes config option.

Hmm..

It was complied with ./configure --without-readline. That's it.

Does postgres801 rpm (postgresql-server-8.0.1-0.1.x86_64.rpm)  comes
with --enable-integer-datetimes enabled by default ? The reason it
prompted me to ask is that, we have postgres801 rpm install in the same
machine in /var/lib dir. If it's enabled by default then I think we
might have started postgres from the rpm binary as opposed to src
binary.

What parameters should I enable if I install postgres on a 64 bit
hardware from src. Seems like x86_64.rpm's enables some parameters which
I'm missing it when I compile it from src.

Thanks,
-Stalin
