Remove obsolete RECHECK keyword completely
This used to be part of CREATE OPERATOR CLASS and ALTER OPERATOR
FAMILY, but it has done nothing (except issue a NOTICE) since
PostgreSQL 8.4. Commit 30e7c175b81 removed support for dumping from
pre-9.2 servers, so this no longer serves any need.
This now removes it completely, and you'd get a normal parse error if
you used it.
