Error while creating new adpator

[VaishnavcveeZ]

Gettting error while running application code for creating adaptor. The error will happen at the 2nd time.

Error -
pq: relation "IDX_casbin_rule_ptype" already exists"

Steps-
1 . Create table for casbin

CREATE TABLE IF NOT EXISTS "casbin_rule" (
    "id" VARCHAR(100) NOT NULL  PRIMARY KEY DEFAULT gen_random_uuid(),
    "ptype" VARCHAR(100) NOT NULL ,
    "v0" VARCHAR(100) NOT NULL,
    "v1" VARCHAR(100) NOT NULL,
    "v2" VARCHAR(100) NOT NULL,
    "v3" VARCHAR(100) NOT NULL,
    "v4" VARCHAR(100),
    "v5" VARCHAR(100)
);

2. Run application with adaptor code

dsn := fmt.Sprintf("host=%s port=%d user=%s password=%s dbname=%s search_path=%s timezone=%s sslmode=disable",
		Host,
		Port,
		User,
		Password,
		DbName,
		Schema,
		Timezone)

xormAdaptor, err := xormadapter.NewAdapter("postgres", dsn, true)
	if err != nil {
		slog.Error("xormadapter.NewAdapter",
			"err", err)
		return err
	}

3. Run the application first time will create an index for colum "ptype" - IDX_casbin_rule_ptype. While running 2nd time will get an error for the existing index.
