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.
