I doubt a sort on a related value will start or commit a transaction and that’s what it apparently tries to do.
Seems Servoy creates a temp table for each transaction. Do you see any messages in the postgres.log ?
Does Servoy connect to the repository with rights to create/drop (temp) tables ?

When you load a foundset by pk list and the list is longer than 200 PKs, servoy will not generate a in-query, instead it will create a temp table, load the PKs in it and join it with your table.
The temp table column name is based on the original column name, unfortunately, when this column name is suspected to be a keyword (like transaction_id) we apply inappropriate quoting which causes your problem.
