stored in a plugin-global array and a pointer to each object was passed around
to the worker functions. This array used to be an array of objects (rather
than pointers) and was realloc'ed every time a new connection was added. Now,
the realloc caused the old pointer to not be valid any more, thus, any but the
last database connection were later accessing memory out of range. This caused
the plugin to segfault if more than one database connection was used.
