Having just tried to restore a 64 bit BSD database to a 32 bit linux

error in my ways.
Now, I need to plan a way forward. From reading of other peoples similar
problems, I now realize that I need a system with identical on-disk
formats. Question is:
Is there a simple way to determine compatibility? (eg. a small
well-defined list of requirements)
initdb on one platform, copy the data directory over to the other
system, and try to start postmaster. It will complain if the on-disk
format is not compatible.
You can also run pg_controlinfo on both systems, and compare the
results. If the "Maximum data alignment", and all the values below it in
the pg_controlinfo output match, the formats are compatible.
