911e702077 implemented operator class parameters including the signature length in ltree. Previously, the signature length for gist_ltree_ops was 8. Because of bug 911e702077 the default signature length for gist_ltree_ops became 28 for ltree 1.1 (where options method is NOT provided) and 8 for ltree 1.2 (where options method is provided). This commit changes the default signature length for ltree 1.1 to 8. Existing gist_ltree_ops indexes might be corrupted in various scenarios. Thus, we have to recommend reindexing all the gist_ltree_ops indexes after the upgrade.

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
