postgresql/contrib/sepgsql/sepgsql.h
Alvaro Herrera f4c4335a4a Add context info to OAT_POST_CREATE security hook 
... and have sepgsql use it to determine whether to check permissions
during certain operations.  Indexes that are being created as a result
of REINDEX, for instance, do not need to have their permissions checked;
they were already checked when the index was created.
