Ticket #1471 – Description
initial v1 5 5 The main benefit would be to be able to use exclusion constraints (introduced in PostgreSQL 9.0) to enforce geometry uniqueness. Right now there is no guaranteed way of doing this and EXCLUSION CONSTRAINTS won't work with functions (so ST_OrderingEquals is out of the question) -- they have to be operators. 6 6 7 http://www.postgresql.org/docs/9.0/static/sql-createtable.html#SQL-CREATETABLE-EXCLUDE 7 http://www.postgresql.org/docs/9.0/static/ddl-constraints.html 8 http://thoughts.j-davis.com/2010/09/25/exclusion-constraints-are-generalized-sql-unique/
