--000000000000b55595059932cb35 Content-Type: text/plain; charset="UTF-8" What do you mean by live queries ? If I'll try to run the following query and cancel it manually(ctrl+c) : select pg_sleep(10) I will see in the logs the following messages : 2019-12-08 17:16:34 IST postgres 30797 LOG: statement: select pg_sleep(10); 2019-12-08 17:16:36 IST postgres 30797 ERROR: canceling statement due to user request 2019-12-08 17:16:36 IST postgres 30797 STATEMENT: select pg_sleep(10); The first message indicates that I run this query (logged because I set log_statements to all) and the two next messages appear because I canceled the query. When it happens to my application I dont see the first message that indicates that I run it and thats what I'm trying to understand. > --000000000000b55595059932cb35 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable <div dir=3D"rtl"><div dir=3D"rtl"><div style=3D"" dir=3D"ltr">What do you m= ean by live queries ?=C2=A0</div><div style=3D"" dir=3D"ltr">If I'll tr= y to run the following query and cancel it manually(ctrl+c)=C2=A0: select p= g_sleep(10)</div><div style=3D"" dir=3D"ltr">I will see in the logs the fol= lowing messages :=C2=A0</div><div style=3D"" dir=3D"ltr"><br>2019-12-08 17:= 16:34 IST postgres 30797 =C2=A0LOG: =C2=A0statement: select pg_sleep(10);<b= r></div><div style=3D"" dir=3D"ltr">2019-12-08 17:16:36 IST postgres 30797 = =C2=A0ERROR: =C2=A0canceling statement due to user request<br>2019-12-08 17= :16:36 IST postgres 30797 =C2=A0STATEMENT: =C2=A0select pg_sleep(10);</div>= <div style=3D"" dir=3D"ltr"><br></div><div style=3D"" dir=3D"ltr">The first= message indicates that I run this query (logged because I set log_statemen= ts to all) and the two next messages appear because I canceled the query.</= div><div style=3D"" dir=3D"ltr">When it happens=C2=A0to my application I do= nt see the first message that indicates that I run it and thats what I'= m trying to understand.</div></div><div class=3D"gmail_quote"><blockquote c= lass=3D"gmail_quote" style=3D"margin:0px 0px 0px 0.8ex;border-left:1px soli= d rgb(204,204,204);padding-left:1ex"><div dir=3D"auto"><blockquote type=3D"= cite"><div dir=3D"ltr"> </div></blockquote></div></blockquote></div></div> --000000000000b55595059932cb35--
