drop constraint/column for v1.4.1

[Miha Radej <miha(dot)radej(at)siix(dot)com>]

hi!

as version 1.4.1 will be released soon, i was just wondering if there 
was any chance of solving this reported issue:

some people i know remove constraints and columns separately and are a 
bit annoyed by the errors they get.

thank you,
