Description: domain check constraint not checked when adding new
column
Details:
Domain check constraint not checked when adding new column.
repro:
add domain 'string' of base type text with non-null constraint
add column of type 'string' to table with existing rows
works; all rows have new column's value set to null
expected:
error: cannot add column due to non-null constraint in domain 'string'
notes:
could not insert a new row with non-null value for 'string' column (as
expected)
trying to add a column of type text with non-null constraint produces
expected error message
