tsvector2

==========

Extended `tsvector` type for PostgreSQL 9.6+. It was implemented to provide better

compression and to remove 1MB size limitation of original tsvector type.

It could be used as transparent replacement of original tsvector and supports

all its functions, operators and index types. Functions that contain `tsvector` in their

names have been changed to `tsvector2`. Full list of these functions specified

below.

Refer to PostgreSQL [documentation](https://www.postgresql.org/docs/current/datatype-textsearch.html)

to get details about `tsvector`. They can be also applied to `tsvector2`.

`tsvector2` specific functions

------------------------------

* `to_tsvector2` (from `text`, `json`, `jsonb` types)

* `array_to_tsvector2`

* `tsvector2_to_array`

* `tsvector2_stat` (should be used instead of `ts_stat`)

* `jsonb_to_tsvector2`

* `json_to_tsvector2`

* `tsvector2_update_trigger`

* `tsvector2_update_trigger_column`

Notice that `jsonb_to_tsvector2` and `json_to_tsvector2` work different on

PostgreSQL 10 and 11. Same applies to `tsvector` functions.

Common functions that could be safely used on both types

--------------------------------------------------------

* `strip`

* `unnest`

* `length`

* `setweight`

* `ts_rank`

* `ts_rank_cd`

* `ts_delete`

* `ts_filter`

Installation

-------------

	make install PG_CONFIG=

	# if you need rum support, install it first:

	# psql  -c "create extension rum"

	psql  -c "create extension tsvector2"
