I wondered about that, but in this case all of my tables are lowercase. Since I've had to clean up mixed case implementations before, I also lowercase everything else as well (functions, views, etc...) I decided to create a test database to see if I could further isolate the problem. I used the following schema in that database: create table people (name char(10), number char(15)); insert into people values ('jenny','8675309'); now I am able to select from the table with no problems, but when I try to use the object browser, I now get this error: java.sql.SQLException: ERROR: no such attribute or function 'oid' at org.postgresql.Connection.ExecSQL(Connection.java:533) On the one hand this seems to imply that DatabaseMetaData.getTables is working ok, but I think that maybe there is a problem with DatabaseMetaData.getColumns?
