Обсуждение: 64bit build vs 32 bit build

Is it possible to use a binary copy of the cluster on a 64 bit build  
of pg 7.4.x that was created on a 32bit bild of 7.4.x

assuming x is the same and integer-date-times are not enabled ?

I doubt it very much. Or put another way, no effort has been put into
making it work...

Have a nice day,

Even more to the point: the reason it won't work is that MAXALIGN is
probably different in the two builds.  Very recent PG releases check
this via a pg_control field, but 7.4.x will probably just crash.
