Engine.DBMetas() returns the size of the column from the database but
Engine.TableInfo() isn't able to guess the column size. For example
when utf-8 charset is used, "`xorm:"TEXT(21846)`" creates a MEDIUMTEXT
column not a TEXT column.
The [oldest unsupported version documentation](https://www.postgresql.org/docs/7.1/sql-comment.html) states that comment on a column is supported.
Update `TestGetColumnsComment` in order to check both MySQL/MariaDB and PostgreSQL.

dumpTables currently badly handles BLOB and TEXT data containing control
characters:
* MySQL will interpret and unescape string literals e.g.`\r` will become
carriage return.
* Postgres will not allow string literals to contain NUL nor will
SQLite so BLOBs will not dump correctly.
* Schemas should not be set on the destination dump
* MSSQL needs the N prefix to correctly ensure that UTF-8 data is
correctly transferred.

Now the below behaviours are allowed.
```Go
var id int64
var name string
has, err := engine.Table(&user).Cols("id", "name").Get(&id, &name)
// SELECT id, name FROM user LIMIT 1
```
```Go
rows, err := engine.Cols("name", "age").Rows(&User{Name:name})
// SELECT * FROM user
defer rows.Close()
for rows.Next() {
var name string
var age int
err = rows.Scan(&name, &age)
}
```

Since `conversion.Conversion` has been referenced by external package, it should not be moved as internal package.

Now `Datetime` support `Datime(6)` to indicate the time scale. For different database , the max scale is not different.
`Datetime` means `Datetime(0)`.

sql server doesn't accept to insert a blank datetime like `0001-01-01 00:00:00`. So that we have a break change here that deleted column should not have a notnull tag.
