Can I use double quoted names with others SGDBs , PostgreSQL ?
or it is specific for Oracle ...
by the way the patch didint work. Its another problem Is not a metter of
"." namespaced name.
Its about if I can or not use '"tb_custom_name"' double quoted string =
' " " '
if I can use that (' " " ') for any database engine, I believe its a bug
...
and even changed the migration manually, the same error occur when create
an INDEX (at my example) ...
so, the error is at the method that generates the db_name string passed for
the ORM to create tables and constraints.
