Hmm, seems I committed a change too hastely.
Hiroki Kataoka also has a similar opinion.

The following statement types are in psqlodbc.h.
Well how about "begin" before TYPE_SELECT
etc and "commit" before TYPE_OTHER
statements ?

/* statement types */
enum {
        STMT_TYPE_UNKNOWN = -2
        STMT_TYPE_OTHER = -1,
        STMT_TYPE_SELECT = 0,
        STMT_TYPE_INSERT,
        STMT_TYPE_UPDATE,
        STMT_TYPE_DELETE,
        STMT_TYPE_CREATE,
        STMT_TYPE_ALTER,
        STMT_TYPE_DROP,
        STMT_TYPE_GRANT,
        STMT_TYPE_REVOKE,
};

Regards,
Hiroshi Inoue
