Hello,

https://wiki.postgresql.org/wiki/First/last_(aggregate)
CREATE AGGREGATE public.first (anyelement)( sfunc = public.first_agg, stype = anyelement, parallel = safe);CREATE AGGREGATEbasetype = anyelement - base element must be in aggregate argument to support new syntax with PARALLEL
Have nice day.
