Postgresql can not work with @Lob type -------------------------------------- Key: HHH-6066 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6066 Project: Hibernate Core Issue Type: Bug Components: annotations Affects Versions: 3.6.1 Environment: Postgresql 8.x and JDBC driver 9.0-801.jdbc4 Reporter: Steve Ni My application needs compatible with some major database such as Oracle, Mysql and Postgresql. I also use hibernatetool ant task to generate DDL. I use @Type(type="text") for string. Before 3.5 version, everything is OK. However, after 3.5 Oracel uses long instead clob type. As Long is deprecated type and the Oracle JDBC driver also has bug to read Long type with hibernate (Stream closed exception). So I try to use @Lob replaces @Type(type=text). The problem is this annotation doesn't work with postgresql. Regarding to this issue, I did some research. The better fix could be Oracle use clob instead of Long. There is not good reason use deprecated type...
