What I find even more suspicious is that the "Primary key" footer shows
up in the table data area.  Looking at print_aligned_text, this seems to
suggest that cells[2] must be NULL --- you would get this kind of
mistake if the number of non-null cells[] entries is not a multiple of
the number of non-null headers[] entries.  But I surely do not see how
describeTableDetails would be setting that cell to null --- it does

			cells[i * cols + 2] = xmalloc(128 + 128);

and xmalloc() will exit() rather than return null.
