Gorm Default value for ID column can't be disabled

Description

The default:(-) tag doesn't work for ID. The ID is always set to be auto increment.

Both gorm:"type:BIGINT;not null;default:(-);" and `gorm:"type:BIGINT;not null;default:null;" doesn't work.

When I look at the postgres table, it has nextval('id_seq'::regclass) which auto increments it.
