CF 9.0.1 "The root cause was that: org.postgresql.util.PSQLException: This ResultSet is closed."

Hi, 

I'm in charge of supporting a legacy application that works with Coldfusion 9.0.1, it has a datasource that was pointing to a postgres 9 database, recently the database was upgraded to postgres 15, when making queries it works fine, but when trying to save or run certain functions I get the following error:

"The root cause was that: org.postgresql.util.PSQLException: This ResultSet is closed."

Any help is much appreciated
