The following bug has been logged on the website:
Bug reference: 9038
Logged by: Craig Macdonald
Email address: craig(dot)macdonald(at)glasgow(dot)ac(dot)uk
PostgreSQL version: 9.2.0
Operating system: Documentation
Description:
The documentation at
http://www.postgresql.org/docs/9.2/static/textsearch-indexes.html
is incorrect in the syntax of CREATE INDEX for GIN and GIST. According to
http://www.postgresql.org/docs/9.2/static/pgtrgm.html the keyword
gist_trgm_ops is also necessary:
test=> CREATE INDEX trgm_idx ON test_trgm USING gist (t);
ERROR: data type text has no default operator class for access method
"gist"
test=> CREATE INDEX trgm_idx ON test_trgm USING gist (t gist_trgm_ops);
CREATE INDEX
