There's a TODO item for this. pgAdmin2 didn't manage the result set, but 
instead would reexecute the given query. This could result in unexpected 
behaviour. Imagine you had a "... where foo < 200", and now you change a 
row's foo to 205. After refresh, the row will be gone. While this is 
technically correct, it's quite irritating.
Due to the complete reexecution, no primary key is necessary. In 
contrast, pgAdmin3's implementation will do updates based on primary 
keys (or oid, if available). You can't extract this information from a 
generic query.
There's internal discussion about the focused audience for pgAdmin3's 
View Data tool. While I see that there are additional wishes about a 
tool to manipulate data, I consider this to be an additional tool for 
data manipulation. Stay tuned.

You're right, there are complications about keyboard handling in 
conjunction with the inplace editing functionality.

It is! Try resizing the row, and use Ctrl-Return to enter a newline. 
This info was missing in the documentation.

Hm, seems the "changed data" check fails... will look at that.
