+1, great idea.
Right now I use the psql :show variable in my .psqlrc for this purpose:
=# \echo :show
SELECT name, current_setting(name) AS value, context FROM pg_settings\g
(format=wrapped columns=100) | grep
=# :show autovacuum

As for the name, I can't think of a better candidate. Any of the
previously suggested list of \dconf, \dguc, \dG, \dcp is fine.
