It's needed for some meta analysis. That's as much as I can say. | To get community buyin into a feature the community - or at least | parts of it - need to understand why its needed. Take a look at these APIs: http://download.oracle.com/javase/6/docs/api/java/sql/ResultSetMetaData.html#isNullable(int) int isNullable(int column) throws SQLException Indicates the nullability of values in the designated column. http://msdn.microsoft.com/en-us/library/ms716289(v=VS.85).aspx NullablePtr [Output] Pointer to a buffer in which to return a value that indicates whether the column allows NULL values. A common and natural question to be answered about result sets. -- Alex -- alex-goncha...@comcast.net -- -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
