Re: How to tell if 64 bit vs 32 bit engine?

There is probably a better way of doing this, but if nothing else try
this:

PostgreSQL executables on Unix:

% file postmaster psql

postmaster: ELF 32-bit MSB executable SPARC Version 1, dynamically
linked, not stripped

psql: ELF 32-bit MSB executable SPARC Version 1, dynamically
linked, not stripped

Checking on the UNIX platform:

AIX:

getconf HARDWARE_BITMODE

getconf KERNEL_BITMODE

HP-UX:

getconf KERNEL_BITS (returns 54 on a 64-bit machine, "Invalid
argument" on a 32-bit machine)

Linux:

uname -a (you'll see i386 on a 32-bit machine, x86_64 on a 64-bit
machine)

Solaris:

isainfo -v (post Solaris 2.7)

Hope it helps,

Michael.

Subject: [GENERAL] How to tell if 64 bit vs 32 bit engine?

I did search the archives for this.... But didn't see a posting that
directly answered the question.

How do I tell if the 32 bit version of PostgreSQL is running on a 64 bit
machine, or if the 64 bit version was installed? Is there a pg_ table
that I can query or a config file I can look in to find out? I found
nothing in postgresql.conf that would indicate this.

Thanks,

Keaton
