"psql -l" really should produce the same results as doing "\l" in the
template1 database.  Does it?  If so, the next thing to look at is
probably whether the pg_class and pg_attribute entries for pg_database
look the same in template1 and in cyspec.  Similarly you could compare
what pg_shadow looks like from different databases, and what the local
system tables have as entries for it.
