[postgis-users] PostgreSQL/PostGIS x64 Error on PostGIS Install

[Donald Kerr]

Ok, Mark, thanks for the confirmation.

I suppose then that I would have to dump the contents of the 32 bit setup
then import to the 64 bit setup which I'm assuming is possible. Offhand, do
you, or does anyone else, know if replication from 32 bit to 64 bit works?
What I'm trying to do is maintain one master data structure on a server
(currently 32 bit) and replicate to various clients; most are 32 bit but
I've just started experimenting with 64 bit clients. I haven't looked at 32
bit to 32 bit replication, never mind complicating matters with 64 bit, as
yet but it's on the To Do list.

Many thanks.

Regards,

Donald

Ah yes. Due to the different variable sizes between 64 and 32 bits, the 
underlying binary structures on disk will be different and therefore 
incompatible.


HTH,

Mark.
