password member of ConnInfo struct was changed to be of pgNAME type.
pgNAME type essetially means a pointer. It's dangerous to simply
copy a pointer to another one and I forgot the operation needed for
password member of pgNAME type and it caused a double free crash later.
I dislike the double free bug and changed CC_copy_conninfo to copy each
item one by one for future changes.

Oops you are right.
