Avoid potential buffer overflow crash
A pointer to a C string was treated as a pointer to a "name" datum and
passed to SPI_execute_plan(). This pointer would then end up being
passed through datumCopy(), which would try to copy the entire 64 bytes
of name data, thus running past the end of the C string. Fix by
converting the string to a proper name structure.
