Essentially, sequence is treated as a separate table for purposes of
permission checking. Its probably _not very hard_ to fix, by forcing check
of the underlying relation instead of check of sequence itself...Whether
its a right thing to do, I'm not sure.

Only queries using LIKE 'foo%', cannot use indices.
Reason: you don't know what foo will collate in different locale, i.e.
there may be foo with umlaut o, which _should_ match 'foo', but you cannot
index this kind of a search...
