Nope, it won't, because \list is a psql-ism.

If you want to exactly duplicate that you could run psql with -E and
look at the queries it issues and copy them (but beware that they are
backend-version-dependent).  However, I was under the impression that
JDBC had its own set of standard metadata inquiry operations.  You'd
probably be better off using those if they cover what you need.

I'm not sure how many JDBC hackers hang out here; you might be better
advised to ask on the pgsql-jdbc list.

Thanks Tom. Your recommendation eventually led me to this thread. The query mentioned there is basically what \list does, just a little simpler. It looks like I can probably use that without worrying about different versions.

As for JDBC, there may be something that gives equivalent information, but I couldn't find it.
