pg_upgrade>-ed hash indexes from previous major Postgres versions must be rebuilt.
-Major hash index performance improvements necessitated this requirement.
+Major hash storage improvements necessitated this requirement.
-Add write-ahead logging support to hash indexes (Amit Kapila)
+Add full text search support for JSON> and JSONB> (Dmitry Dolgov)
-This makes hash indexes crash-safe and replicated, and removes the
-warning message about their use.
+This is accessed via ts_headline()> and to_tsvector. RIGHT SECTION?
-Improve hash bucket split performance by reducing locking requirements
-(Amit Kapila, Mithun Cy)
+Add
SP-GiST> index support for INET> and CIDR> data types (Emre Hasegeli)
-Also cache hash index meta-information for faster lookups. Additional
-hash performance improvements have also been made.
+These data types already had GiST support.
-Allow single-page hash pruning (Ashutosh Sharma)
