Обсуждение: can be database files be copied using 'cp' between hosts with different endianess?

Hello,

I have a quesion - suppose I have sparc box and x86 box running same
release of postgresql compiled with same options. Can I simply copy database
directory between hosts (of course when postgresql server is stopped on both
boxes)?

BTW Mysql (MyISAM) and sqlite allow this.

Thanks for your answer in advance!

Absolutely not.

That's a pity..

I've been able to do Solaris x86 -> Linux x86 copies. But I'm pretty
sure Sparc & x86 are not compatible endian-wise so hence the data is not
stored the same. Other attempts that have failed -- Linux x86 32bit -->
Linux x86_64.
