<fileversion>
The fileversion option can be set to a major version number of c-treeRTG (i.e. 2). The default value of fileversion is the major version number of the current c-treeRTG version (e.g. 3). If fileversion is specified in the configuration file, the default values of all the other configuration options are reset to the default value of the c-treeRTG version specified.
For example, if
<fileversion>2</fileversion> is specified in a configuration file while running c-treeRTG version 3, the default value for the <rowid size> attribute is changed from 8 to 4. Also the default value of the <keycompress vlennod> attribute is changed from 1 to 0 and the implicit value of <keycompress/> is changed from <rle/> to <leading/><padding/>.
Note - the compatibility with previous versions might be affected also by the
PAGE_SIZE setting in the server configuration. Be sure to use the same page size between the current c-tree version and the previous c-tree version you want to be compatible with.
