But *incompatible* with SQL truncation of qualified names. Remember
that you can refer to something by any portion of its qualified name,
such as:
pg_extensions.postgis.submodule.special_type
postgis.submodule.special_type
submodule.special_type
special_type
... are all valid. Which is fine until you think that we could have a:
pg_extensions.pg_tap.submodule.special_type
or even a:
schema submodule.special_type
which would confuse both the search path and the user. What this means
is that all schema names would have to be unique, whether they are
nested or not. Which makes subschema *within* an extension rather useless.
