We should do all of those.  However, we have to start somewhere.

Therefore, I like the idea of having a switch, like:
\advice mysql
\advice db2
etc.

ALSO, I'll point out that a page in our official documentation with
extensive docs on commands and migration issues would be far more
helpful than any amount of psql messages.  Just sayin'.
