Dear Rich:

    Sorry this isn't a complete answer.  If you really need SQL
(rather than \d inside psql) there is a way to find out the SQL commands
psql uses to perform its special commands.  This subject has been on
the newsgroup in the "recent past" -- sorry, don't have anything exact.
Alternatively you can invoke psql with a shell script, something like:
    psql -s <database name> -t <table name>
which will cause the schema to be sent to stdout.  I'm not sure what
you want to do via libpq, though once you have the SQL strings you could
use any number of methods to access the schema.

Hope this helps!
