Hmmm.. Teach me to read the docs. :-) There's no way to set opckeytype. So hwo about: CREATE OPERATOR CLASS <name> [DEFAULT] FOR TYPE <typename> [AS <stored type>] USING <access method> WITH <list of operators> AND <list of support functions> With AS <stored type> present, the opckeytype column gets set to that type name's oid. > New keywords are "CLASS" (SQL99 reserved word) and "REPEATABLE" (SQL99 > non-reserved word, see below for usage). > > <name> is the class's name, and <typename> is the type to be indexed. > <access method> is the assosciated access method from pg_am (btree, rtree, > hash, gist). > > The presence of [DEFAULT] indicates that this operator class shold be made > the default operator class for the type. > > <list of operators> is a comma-delimited list of operator specs.

"needs_recheck" is not handled as a keyword, but as an IDENT which is examined at parse time. > <list of support functions> is a comma-seperated list of functions used to > assist the index method.
