I have been actively maintaining the driver off and on since 1999 or so. Recently we have had a flurry of activity and one of the things I noticed was the surprise that PostgreSQL didn't support X or did Y in some unexpected way. Sometimes we are a bit too complacent, and accept things the way they are.
I am wondering what could the server do better that would help JDBC?
Obviously streaming a column is one. Possibly rowid's. Anything else ?
