MCR schema migration stage 4: Migrate External Store URLs (wmf production)
Open, NormalPublic

Description

We should migrate data stored in the External Store away from the text table: The External Store URL that is contained in the text blob can be written to the cont_address field (possibly with a prefix, to be decided, see External Store Integration). Then the corresponding rows can be deleted from the text table.

I am interested on this happening at some point, I just saw lots of revision data (not metadata) stored on the text table and its impact on a quick database recovery.
