I have an issue where even though I break a large BYTEA object up into multiple pieces, the ODBC driver just rejoins the pieces in memory and tries to send it all out at once. I took a look at the code and sure enough the driver just keeps reallocating memory for each chunk of data that I add. Can I assume Postgres has no mechanism to send this data across the wire in pieces? Are there any common practices for dealing with this? As it is, in one environment I can only transfer files around 50MB before I start receiving out of memory errors. The same program running against Oracle and SQL Server works great.
