What this is reflecting is that backslash commands have their own weird
rules for processing double quotes. What I was concerned about was that
double quotes in SQL are normally used for protecting mixed case, and
you don't need that for \c:

regression=# create database "FooBar";
CREATE DATABASE
regression=# \c foobar
FATAL: database "foobar" does not exist
Previous connection kept
regression=# \c FooBar
You are now connected to database "FooBar".
FooBar=#

The fact that there are double quotes around the database name in the
"You are now connected..." message is *not* meant to imply that that is
a valid double-quoted SQL identifier, either. It's just an artifact of
how we set off names in English-language message style. In another
language it might look like <<FooBar>> or some such.

My opinion remains that you should just print the user and database
names as-is, without trying to inject any quoting into the mix. You're
more likely to confuse people than help them if you do that.
