> Metastore direct SQL is currently disabled for any queries running inside external transaction (i.e. all modification queries, like dropping stuff).
> This was done to keep the strictly performance-optimization behavior when using Postgres, which unlike other RDBMS-es fails the tx on any syntax error; so, if direct SQL is broken there's no way to fall back. So, it is disabled for these cases.
> It is not as important because drop commands are rare, but we might want to address that. Either by some config setting or by making it work on non-postgres DBs.
