Hi,

When executing a prepared insert statement and using SQL_DATA_AT_EXEC parameters that will be sent with SQLParamData and SQLPutData, the driver will leak memory for parameters. The memory will not be deallocated not even the handles are freed and the program disconnects from the database.

I am attaching a small project to demonstrate the bug. You can also browse the project at https://hub.darcs.net/mihaigiurgeanu/psqlodbc-insert-leak

Thanks for the report.
It would take some time to examine the issue because I am very busy now,
