Pushed after further hacking on the documentation and test cases.
I went ahead with the "value" to "offset" terminology change, too.
You mentioned upthread that you were interested in adding more in_range
support functions. I think it'd be a great idea to get that done for v11,
because according to my reading of the SQL spec, it expects "RANGE offset
PRECEDING/FOLLOWING" to work for any numeric type. See SQL:2011 7.11
<window clause> syntax rule 11-a-iii:
iii) The declared type of [the sort column] shall be numeric,
datetime, or interval. The declared type of [the offset] shall be
numeric if the declared type of SK is numeric; otherwise, it shall
be an interval type that ...
So we need in_range functions for float4, float8, and numeric if we
really want to claim with a straight face that we cover all of SQL:2011
here. I think that ought to be a small enough addition to deal with in
the final v11 commitfest, if you have time to prepare a patch this
month.
