Perhaps that can be solved by displaying the constraint name in the
table:
55489 16devel 1776237=# \d tab
Tabla «public.tab»
Columna │ Tipo │ Ordenamiento │ Nulable │ Por omisión
─────────┼─────────┼──────────────┼────────────────┼─────────────
a │ integer │ │ tab_a_not_null │
(Perhaps we can change the column title also, not sure.)
