Compressed Blobs (blobz)

In Texis version 8 and later, the blobz SQL type was added. This type is similar to the blob type, in that it is intended for large, infrequently-accessed fields and is stored in a separate .blb file. However, blobz fields may be compressed on disk to save space, and are automatically uncompressed when read and converted to another type.

Caveat: A table created with (a) blobz column(s) should not be accessed nor modified by Texis version 7 or earlier, or errors and/or corruption may result. Some versions prior to 8 may be able to handle blobz data; however support and/or correct behavior is not ensured.
