      Description

      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.
