For more complex search/replace operations, 8.1 provides an interesting
function, named 'regexp_replace'.
It probably goes unnoticed because although there is a small reference in
the manual in section

update media_instance set location=replace(location,'v.','')

Hello-
I have a column of data with the wrong prefix for many items.
The wrong entries are entered ' /0/v.myimage.jpg'
While the correct ones are ' /0/myimage.jpg'
