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);

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
operations <, <=, =, >=, > using left_bound, right_bound and prune branches of
a tree using signature.
