well, these pg_get_..._ddl() functions will be cool for compare/clone
schemas in a multi tenant world.
Instead of dump/sed/restore a schema to create a new one, I could use
something like
select pg_get_table_ddl(oid) from pg_class where nspname = 'customer_050'
and relkind = 'r' union all
select pg_get_constraint_ddl(oid) from pg_constraint inner join pg_class on
... where ... union all
select pg_get_trigger_ddl(oid) from pg_trigger inner join pg_class on
... where ... union all
...
And pg_get_policy_ddl() will be part of these union all selects
Because that would be good to worry about create that only if it does not
exists or drop first too.

Marcos
