MySQL 5.0 and 5.1 Support - Mastering phpMyAdmin 3.1 for Effective MySQL Management - page 272

Changing repository data
In case the MIME type for the uploaded data was not interpreted correctly, it's
possible to modify it by clicking this link and typing in the correct type. Note that
this feature is a work in progress in version 3.1.1.
Finally, when editing this row, we'll see a Remove BLOB Repository Reference
option. Putting a check mark on this option and saving the row tells the PBMS
engine to forget about this reference, eventually eliminating the BLOB data from
the repository.
Summary
MySQL 5.0's new features helped the product comply with standards. Even
though phpMyAdmin has limited support for these features (especially lacking
a syntax-oriented editor), it has a basic set of features to work with views,
routines, triggers and information_schema , and to display profiling information.
phpMyAdmin also supports MySQL 5.1 partitions and events, the PBXT storage
engine, and BLOB streaming. The next chapter covers administration of a MySQL
server, focusing on the management of user accounts and privileges.
