Hi,
I'm trying to setup Bucardo to do a master-master replication between two PostgreSQL servers. However, it looks like when it tries to execute a query involving DISTINCT and a column with a data type of "polygon", the following error is thrown by PostgreSQL:
ERROR: 42883: could not identify an ordering operator for type polygon
I assume a default operator class for polygon needs to be defined using "CREATE OPERATOR CLASS" (http://www.postgresql.org/docs/8.1/static/sql-createopclass.html). Does anyone have an example of an appropriate operator class definition for this data type?
Thanks,
Lawrence
