Bug reference:      8837
Logged by:          Kurt Rayner
Email address:      kurt@alphasoftware.com
PostgreSQL version: 9.3.2
Operating system:   Windows
Description:

The PostgreSQL ANSI ODBC driver reports 42P18 - ERROR: could not determine
data type of parameter $<n>; when preparing SQL with an expression of the
form:

  <bound parameter> IS NULL.

This is a breaking change to existing code that depends on being able to
check the NULL-ness of a parameter.

This behavior is new as of 9.03.01.00.
