Try

replace_rcpt sql_query {
  import pg_con
  lookup "SELECT address AS addresses FROM aliases WHERE alias = $1"
}

It is not necessary to use STRING_AGG, sql_query already handles multiple rows in query result as multiple values.

Yes, its working, thank you! Reason for opening this request was this sentence in documentation:

https://maddy.email/reference/table/sql_query/

lookup query
Required.

SQL query to use to obtain the lookup result.

It will get one named argument containing the lookup key. Use :key placeholder to access it in SQL. 
The result row set should contain one row, one column with the string that will be used as a lookup result. 
If there are more rows, they will be ignored. If there are more columns, lookup will fail.
If there are no rows, lookup returns "no results". If there are any error - lookup will fail.

hence I must admit I didn't try it without STRING_AGG() 😵‍💫

Sorry for bothering you with nonexistent issue!

Woops, that's outdated and should be fixed.
