\d schema.table crashes

Reproduce el fallo con %sql \d pg_catalog.pg_class mediante ipython-sql contra PostgreSQL 11.5 y después inspecciona el resultado de pgspecial en la llamada a sql/run.py que se muestra en el trace. Compáralo con la ruta funcional %sql \dn pg_catalog; se considera terminado cuando el comando de tabla deja de generar AttributeError y devuelve su resultado.

I am using the latest version of pgspecial with postgresql 11.5 on Manjaro Linux.

I am using pgspecial from ipython-sql

Once I connect to my DB, I can run commands such as:

%sql \dn pg_catalog

and get proper output

But, if I try to run a command such as:

%sql \d pg_catalog.pg_class

it crashes with the following stack trace

`

It doesn't matter what table I use.
