^^^^^^^^^^^^^^^^ - in 6.3
Well, this means that problem lies in large objects...
I never used them... I assume that new relation and index
is created for each LO. If this is right then we have memory leak
in relation cache (heap_close doesn't flush relation from cache).
Also, as I see now, LO interface uses its own memory context:
TBL_FREE_CMD_MEMORY can't help here -> all allocation must be
freed "manually".
Unfortunately, I haven't time...
