Hi,
This is the expected behavior, like that sql statements with différent
values are shared in pg_stat_statements ...
There is no parameter to change this, if you really want query paramèters
you néed to have a look at statements logging, but be carrefull this can
generate a huge volume of log files depending on your workload ...
See log_statements at
https://www.postgresql.org/docs/9.5/static/runtime-config-logging.html
Regards
PAscal
