Hi,

Working on ST_OffsetCurve I found that it's called in
LocateBetween/LocateAlong. Parameter called `offset` is listed in docs, but
no examples or usability explanation is there. ISO standard mentioned in
description seems to not have description for LocateBetween/LocateAlong too.

https://postgis.net/docs/ST_LocateBetween.html

What is its purpuose? Can it be documented and proved, or removed?
