Hi all, I'm using the temporal contrib package that creates the period type and a bunch of operators in postgresql 8.4.5. I plan to use the same code against 9.0 so if anything differs between the two regarding this issue please let me know. In psql the \do command shows this public | = | period | period | boolean | and yet when I do a select distinct with a join I get QueryLogger - *** error. org.postgresql.util.PSQLException: ERROR: could not identify an equality operator for type period If I leave the period column out of the select list then it works fine. Did I install it wrong? Or is something else going on? tia arturo -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
