Adjust the APIs for GIN opclass support functions to allow the extractQuery()
method to pass extra data to the consistent() and comparePartial() methods. This is the core infrastructure needed to support the soon-to-appear contrib/btree_gin module. The APIs are still upward compatible with the definitions used in 8.3 and before, although *not* with the previous 8.4devel function definitions. catversion bump for changes in pg_proc entries (although these are just cosmetic, since GIN doesn't actually look at the function signature before calling it...) Teodor Sigaev and Oleg Bartunov
