I would argue that we should likewise not allow them in plpgsql's MOVE,
although this is more of a judgment call than is the case for FETCH.
I just don't think it's a good idea to provide two redundant ways to do
the same thing, when we might want to make one of the ways mean
something else later. There's no upside and there might be a downside.
It's question. There are lot of links to FETCH in doc, and we support from
FETCH direction only subset. It needs at least notice in documentation. When
I testeid MOVE I found an form
MOVE FORWARD 10 ... more natural than MOVE RELATIVE 10 and if we support
MOVE FORWARD ... then is logic support MOVE FORWARD n ,
else FORWARD, BACKWARD are nonstandard and MOVE statement too.
