[db] Handle placeholder syntax in different databases

[at15]

• mysql and sqlite use ?
• postgres use $1, $2 ... etc. it is not handled by postgres driver I suppose
• https://github.com/Masterminds/squirrel handles this
• https://github.com/jmoiron/sqlx/ also handled this, it also has more extensions
  • scylladb made one for cassandra after it https://github.com/scylladb/gocqlx, it is using reflection
  • [ ] I don't know if they cache reflection also I remember there are code generation for query & unmarshaling result in go
