Problems with pg_options. - Mailing list pgsql-general

Hi everybody.

I  have pg_options:
verbose=1
query=1
syslog=1
When i added options:
executorstats or
plannerstats or
parserstats,

postgres send message:

Backend message type 0x44 arrived while idle
Backend message type 0x44 arrived while idle
student_kad=> \d
PQsendQuery() -- There is no connection to the backend.

How can i resolve this problem ?

Thank you for your answer.
