In plpgsql, if you write
OPEN var BLAH
you can an error message like this:
ERROR: syntax error ...
DETAIL: Expected "FOR", to open a reference cursor.
But what is a "reference cursor"? Isn't this rather saying "... to open a
cursor, a reference to which will be stored in your variable"? Anyone got a
better idea for a wording?

The documentation uses the phrase "unbound cursor". +1 for changing it
--- I don't see any other uses of "reference cursor", except in
pg_type.h where type "refcursor" is commented that way. And that should
probably read "reference to cursor".
