This doesn't seem to be a bug of PostgreSQL.

The messages don't seem to be of PostgreSQL but some googling told me
that it comes from JDBC driver.  The underlying Java VM doesn't offer
enough amount of heap memory for the result.  Maybe you can use
setFetchSize() to limit the number of result sent from the server at
once.

If so you need to make sure you are in a transaction, otherwise setFetchSize does not do anything
