Hi, Well i create a new type. I want indexing my new type but i can't , postgresql erro : my type has no default operator class So i use the following query in order to have default operator: INSERT INTO pg_opclass(opcname,opcdeftype) select 'ean13_ops',oid from pg_type where typname = 'ean13' ; So the new error with postgresql when i try to create an index on my new type is : opclass "ean13" not supported by access method btree So I think i forget some definition function in my c program in order to use index . I 've got operators for my type ( > , < , == and so on ) Can you help me ??? Thanks in advance, Best regards, PEJAC pascal
