* use doobie 0.9.0 Fragment-in-Fragment interpolation in json-api db-backend
Since tpolecat/doobie#1045 (and therefore 4ca02e0eb6) doobie has
supported interpolating fragments in fragments. We've used this feature
for several fragments written since #7618, but have left the ones
written before alone to use ++. Here we change that where it
meaningfully clarifies the SQL subexpression.
Note that this does not entail a Put or Write instance for Fragment.
You cannot abstract over Fragment and arbitrary interpolated data in
this way, because Fragments are not treated as positional parameters;
that would mean being able to put arbitrary SQL substrings in positional
parameters.
