I just searched through the 2008 spec for a slice/subset operator and came up
empty. It seems to define a bunch of predicates for multisets, but not much for
arrays.
And looking again at the options, I'm *okay* with %, but not keen on %> anymore
(I could see a future where %> and <% it as complement @> and <@ by confirming
the presence of keys in an hstore:
bool = hstore %> text[];
So, frankly, I'm coming back to what Florian has suggested here. What about
calling it slice?
hstore = slice(hstore, text[]);
It'd be nice to have one for arrays, too:
anyarray[] = slice(anyarray[], int[]);
An operator could always be added later if a good one appeared.
Okay, no more bikeshedding for me on this issue. I'm covered in paint.
Best,
David
