Parameterized queries that are not prepared statements

[jrylander]

Please excuse me if this been discussed already (I have searched). I have recently explored the possibility of using a connection pooler for Postgresql named PgBouncer. This works most efficiently if each sql call can be independent but that is not the case if using stored procedures. The only alternative if I am not mistaken is using non parameterized simple strings which of course is very clunky and possibly unsafe.
Have it been discussed to use e.g. PQexecParams (https://www.postgresql.org/docs/current/libpq-exec.html) or other ways of executing queries with parameters but not using prepared statements?
