Use a package 'com.vladmihalcea:hibernate-types-52:2.8.0' or add your database dialect to yml file in resources:

@Entity
@TypeDefs({
        @TypeDef(name = "string-array", typeClass = StringArrayType.class),
        @TypeDef(name = "json", typeClass = JsonStringType.class),
        @TypeDef(name = "jsonb", typeClass = JsonBinaryType.class)
})
public class Post implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Type(type = "string-array")
    @Column(columnDefinition = "text[]")
    private String[] tags;
