Hi, I have used the xwiki-db-0.9.2-pgsql.sql(from xwiki site) for my postgresql database in xwiki-0.9.841(in Java 1.4.2/Tomcat 5.0.28) successfully. Recently I upgraded to the latest source code (now I am using Java 1.5_6 and Tomcat 5.5.16) but I started to have the following errors when I access xwiki. I am still using the previous xwiki db I created: java.sql.SQLException: ERROR: column xwikidocum0_.xwd_title does not exist at org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryEx ecutorImpl.java:1365) at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutor Impl.java:1160) at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.ja va:172) at org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Stat ement.java:387) at org.postgresql.jdbc2.AbstractJdbc2Statement.executeWithFlags(Abstract Jdbc2Statement.java:328) My question is: are there any db schema changes since 0.9.481 and where can I find a new db schema? thanks -Jimmy
