Which could be because you're doing something nasty with one of the
"autocommit=off" clients.  Most of the client libraries implement
this by doing "commit;begin;" at every commit.  This means you have
way more idle in transaction connections than you think.  Look in
pg_stat_activity, assuming you've turned on query echoing.
