Add identifying info to FETCH FORWARD statements from 'fold' query executions

[rdwebster]

When executing SQL queries with the 'fold' family of functions, could there be some way to control the SQL generated for the "FETCH FORWARD" statements?

If I look at the corresponding activity on the Postgres server, I see a lot of these:
FETCH FORWARD 256 FROM temp1

This makes it quite difficult to match up DB activity with what triggered it.
If one of these queries is running for an unexpectedly long time, I'd like to be able to match it up with our logs somehow.

Perhaps the name of the CURSOR could be optionally provided in the FoldOptions.
Or maybe allow a SQL comment to be provided for the FETCH FORWARD statement.
