Support for uuid and CHARACTER varying[] in Postgres database about gen

[alexj212]

• v0.9.23 (07/10/2020)
  • Added postgres types: bigserial, serial, smallserial, bigserial, float4 to mapping.json

[GeekEast]

Suggestion

• for uuid, suggest to generate type as uuid.NullUUID
• for CHARACTER varying

type Company struct {
    Tags sql.NullString `gorm:"column:tags;type:VARCHAR;default:'{}';" json:"tags"`
}

@GeekEast I added uuid support for postgres handling it as a string - Looking into CHARACTER varying

[dwgeneral]

CREATE TABLE order_details (
    order_id smallint NOT NULL,
    product_id smallint NOT NULL,
    unit_price real NOT NULL,
    quantity smallint NOT NULL,
    discount real NOT NULL
);

It seems like gen doesn't support the real type of Postgresql

table: order_details unable to generate struct field: unit_price type: FLOAT4 error: unknown sql type: float4
table: order_details unable to generate struct field: discount type: FLOAT4 error: unknown sql type: float4
