Well idle in transaction is ALWAYS a code issue. You have code that is
executing that is starting a transaction, leaving the connection open
while not closing (committing/rollingback) the transaction.

You could turn on query logging and make sure pid and timestamp is in
the log_line_prefix. They you can see what pids are idle in transaction
and trace to what the last query was.

Any update/delete to that table is going to cause bloat, autovacuum
cleans that up. If it can. If it can't, it will just continously grow.
