Postgres 11.2 given error "Failed to initializetransaction_deferrable to 0"

Hi All,

I have installed postgres 11.2 and i am executing parallel queries with huge
data. So while executing, sometimes postgres given error "Failed to
initialize transaction_deferrable to 0" and sometimes query executes
successfully. Following error log generated by postgres.

LOG:  SET TRANSACTION [NOT] DEFERRABLE must be called before any query
2019-10-29 18:43:03.921 FATAL:  failed to initialize transaction_deferrable
to 0
2019-10-30 05:43:03.924 ERROR:  failed to initialize transaction_deferrable
to 0
2019-10-30 05:43:03.924 CONTEXT:  parallel worker
2019-10-30 05:43:03.924 STATEMENT:  <Query>
2019-10-30 05:43:03.924 LOG:  background worker "parallel worker" (PID
31604) exited with exit code 1

I just need to know about this bug.
