/** Passing arbitary connection string to ODBC Driver Manager is insecure, for the following reasons:
* 1. Driver Manager like unixODBC has multiple bugs like buffer overflow.
* 2. Driver Manager can interpret some parameters as a path to library for dlopen or a file to read,
* thus allows arbitary remote code execution.
*
* This function will throw exception if connection string has insecure parameters.
* It may also modify connection string to harden it.
*
* Note that it is intended for ANSI (not multibyte) variant of connection string.
