Thanks for the input! I already have written the introspection SQL for all the current databases in my related project, xo, that I'm planning on putting into this, so I'm not really worried about the implied additional complexity. As well, I don't think that implementing the backslash commands is too difficult, and the real point/motivation is to have a standardized interface for all the databases. I've used both pgcli and mycli, which are nice (thanks!), but I need a single common interface that supports all the databases that xo supports (which is entirely why this was written, as there's no pgcli/mycli equivalent for mysql/sqlite3/oracle -- until now).
