Oh, I didn't noticed that I've posted updated patch off-list. So, there is
repost of that version of patch. List of changes is below:
1) Distinct slot is used for length histogram.
2) Standard statistics is collected for arrays.
3) Most common values and most common elements are mapped to distinct
columns of pg_stats view, because both of them are calculated for arrays.

Now, it's hard for me to give to it as much time as I would like to. But I
hope to present improved comments and testing until end of october.
