Hello Sergei,
Aggregate functions have syntax for ordering: just "select array_agg(i order by i) from ...." Described here: https://www.postgresql.org/docs/current/sql-expressions.html#SYNTAX-AGGREGATES
Great, that's indeed enough for my usage, thanks for the tip!The questions remains, why not provide an "array_sort", which could be useful in other contexts?
