I'm in the process of moving a large database from an in-house Win32 server to a co-located Ubuntu Linux server. The data's in constant use, so I can't really bring the server down for more than a half hour or so, and I'd like to go ahead and use a base backup + WAL restore strategy to sync the servers up before flipping the switch. After copying over my base backup and setting ACL appropriately, when I go to start the server on Linux it fails with a message in the log stating that the cluster (binary copy from the W32 server) is initialized MAXALIGN 8 and the server is compiled MAXALIGN 4. A search of the Docs tells me that I can compile the server with a different MAXALIGN, but the install docs don't give any indication how this is achieved. Is there a configure or gmake option I can feed, or do I need to change a line in one (or more) of the source files? Or is there a compelling reason (I'm absolutely ignorant here) to do a dump and restore instead of the binary copy because MAXALIGN 4 is better for performance/security/fill-in-the-blank? Or is a binary copy move from W to L hopeless even if this particular issue isn't? Thanks Sean
