Release Date: 2013-11-22
The following command would upgrade the current pg_bigm 1.0 to 1.1.
ALTER EXTENSION pg_bigm UPDATE TO '1.1';
Kindly note that if an existing index uses "gin_trgm_ops" in the database then it will not possible to upgrade from 1.0 to 1.1 since the operator class "gin_trgm_ops" is dropped in version 1.1.
Make pg_bigm support PostgreSQL 9.2 and 9.3 (Fujii Masao)
Enable pg_bigm to coexist with pg_trgm (Beena Emerson, Fujii Masao)
Previously, the modules pg_trgm and pg_bigm could not co-exist in the same database because both declared the same operator class gin_trgm_ops. This operator class was dropped in pg_bigm 1.1
Support text similarity search (Amit Langote, Fujii Masao, Beena Emerson)
Add bigm_similarity() function (Amit Langote, Fujii Masao, Beena Emerson)
Improve handling of multibyte characters (Beena Emerson)
On a platform that does not have the wcstombs() or towlower() library functions, this could result in an incompatible change in the contents of pg_bigm indexes for non-ASCII data. In such cases, REINDEX those indexes to ensure correct search results.
Add English version of documents (Beena Emerson, Fujii Masao)
Add regression tests for all functions and parameters of pg_bigm for English and Japanese language (Fujii Masao, Beena Emerson)
Add regression test to check co-existence of pg_bigm with pg_trgm (Beena Emerson, Fujii Masao)
A new command "make installcheck-trgm" will check if both modules can co-exist
Fix bug in enable_recheck with gin_key_limit = 1 (Fujii Masao, Beena Emerson)
Get rid of the restriction of available database encoding and locale (Beena Emerson, Amit Langote, Fujii Masao)
