I've read this: http://ibexpert.net/ibe/index.php?n=Doc.DefinitionBlob
and I'd like to ask: If I have large blob data in my BLOB field in DB - it is stored in "blob 2 level" manner. But what about changing data size (by updating this column) to something smaller - something that can fit "blob 0 level" - will FB change storage manner to "level 0" ? When will it happen - immediately or after backup restore ? What will happen with old blob data pages ? b
