I have try select string_agg(partname,':') from part_tab; its return same,
ERROR: function string_agg(bigint, unknown) does not exist LINE 1: select string_agg(part_id,':') from part; ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts. i thought string_agg and array_agg same, is it right..?
