    Hi!
    Table source contains integer column. Its values should be passed
      to function for selecting data from other table.

      I tried

              CREATE OR REPLACE FUNCTION
      public.TestAddAssetTransactions(dokumnrs int[]) 

               RETURNS int AS

              $BODY$

              with i1 as (

              INSERT INTO bilkaib (dokumnr)

              select dokumnr  from dok where dokumnr in (select * from
      unnest(dokumnrs))

              returning *

              )

              select count(*) from i1;

              $BODY$ language sql;

              create temp table bilkaib (dokumnr int ) on commit drop;

              create temp table dok (dokumnr serial primary key ) on
      commit drop;

              create temp table source (dokumnr int ) on commit drop;

              insert into source values (1),(2);

          select TestAddAssetTransactions( (select ARRAY[dokumnr] from
      source)::int[] )

      but got error

      > ERROR: more than one row returned by a subquery used as an
      _expression_

Probably you want an array_agg and not an array
select TestAddAssetTransactions( (select array_agg(dokumnr) from source) )
