I'd rather have a "safer" value in the ballpark of 128, and if that's too low for you, 1000 max, but nowhere above that.  Currently pgJDBC eats RAM like it's unlimited. I would like that just as much as you do, but it isn't ;)

Also, why not honor the fetchSize on every SELECT statement regardless of auto-commit ? 

Auto-commit should only affect writing statements (INSERT/UPDATE/DELETE), not read (SELECT) statements, right ? Why is auto-commit even relevant to honoring the fetchSize in the first place ? I'm confused.
