Re: Migrating from 32 to 64 bit

["Medi Montaseri" <montaseri@xxxxxxxxx>]

But theoretically speaking, 32 or 64-bit ness of the application (ie the postmaster server) should not influence the data types offered by a particular DB version. That is the semantics of data types and cpu-arch (register width, big endian, little endian, sparc, mips, x86), etc ) offered by a particular DB version should be orthogonal. 

A practical example is when I first begin my business on a Mac, then I move the database to a Sun and then on to a mainframe....

Dump and restore. Using the old data dirs won't work.
