24058	Sequence is dropped from AutoIncrement field on postgre when changing verbose name	hakib	nobody	"After adding `verbose_name` to an id field with auto increment I started getting errors on null PK. Further investigation reviled that after applying migration the id column was altered in a way that caused the sequence to be dropped. As far as i can tell this is an issue only on postgre.  

Altering the id field manually to associate the sequence solved the problem.

On my dev machine using sqlite this issue is not happening.
