Incorrect checksum in the file checksum error for postgres 9.1.3 data created in osx-Lion and access to it in osx-snow-leopard

Question

I get the following error when trying to start postgres using data created on another Mac machine. FATAL: Incorrect checksum in the control file.

The postgres version is 9.1.3, and the data initialized in the snow leopard does not work in Lion and vice versa. I do not encounter this problem for postgres v9.0.1. is there any configuration in postgres 9.1.3 that fix this problem?

Answer 1

You cannot move between systems with different operating systems. Compiled versions can have different alignment, etc. Dump the old and restore to the new.
