idle in transaction

Hi All,
Can somebody help me to understand the below given idle in transaction?

SELECT * FROM pg_stat_activity where pid = 2161513;
-[ RECORD 1
]----+-----------------------------------------------------------------------------------
datid | 37490141
datname | prod
pid | 2161513

I would like to understand the following query found in the
pg_stat_activity.
I see this particular process always active but not doing anything in the
BDR network. How do I find out what query is it running?

SAVEPOINT _per_query_svp_;DEALLOCATE "_PLAN0x7fdd58004550";RELEASE
_per_query_svp_
