Re: JDBC and positioned updates

1) Have you considered using "updatable ResultSet"?

Here's a sample:

https://github.com/pgjdbc/pgjdbc/blob/32f513370306529005cb36d968f8e415f4a88aec/pgjdbc/src/test/java/org/postgresql/test/jdbc2/UpdateableResultTest.java#L301-L303

2) >   WHERE CURRENT OF cursor_name

ResultSet implementation fetches result rows in batches, thus "current
of" at the database side might point to a slightly different row than
ResultSet at the java side.

3) You do not expect high throughput of that kind of API, do you?
Updatable ResultSet is not using batching, so each update would result
in a database roundtrip.
