  Various indices could be created to speed up execution of operations:
  
    * B-tree index over ltree:
!     <, <=, =, =>, >
    * GiST index over ltree:
!     <, <=, =, =>, >, @>, <@, @, ~, ?
      Example:
      create index path_gist_idx on test using gist (path);
    * GiST index over ltree[]:

  ltree:
  For ltree we store LPS in a B-tree, implemented using GiST. Each node entry is
  represented by (left_bound, signature, right_bound), so that we could speedup
! operations <, <=, =, =>, > using left_bound, right_bound and prune branches of
  a tree using signature.
