It is there, if you look into read_cursor_args().

This appears to be the only place in pl_gram.y where we don't treat '='
and COLON_EQUALS interchangeably.

I was about to suggest that we should accept "=" here too, but on second
thought that could break existing code, if anyone's using boolean equality
expressions in cursor arguments.  So we'd better accept the inconsistency.
