Standardize error reports in unimplemented I/O functions.
We chose a specific wording of the not-implemented errors forpseudotype I/O functions and other cases where there's littlevalue in implementing input and/or output. gtsvectorin nevergot that memo though, nor did most of contrib. Make these allfall in line, mostly because I'm a neatnik but also to removeunnecessary translatable strings.gbtreekey_in needs a bit of extra love since it supportsmultiple SQL types. Sadly, gbtreekey_out doesn't have theability to do that, but I think it's unreachable anyway.Noted while surveying datatype input functions to see what wehave left to fix.
