[Pgpool-general] syntax error at or near "send" at character 1

[Marcelo Martins]

Hi,

I'm wondering why this is caused when I run the following as a quick  
test.
can this syntax error cause any DB mismatch and make the DB get out of  
sync cause on a real scenario,  one time a few minutes after that  
showed in the logs I saw a kind mismatch over and over until I pulled  
node 1 out.

pgpool server:
nast=# set statement_timeout TO 100;
SET

nast=# SELECT count(*) from instance group by id order by id ;
ERROR:  canceling statement due to statement timeout

node 0:
2009-03-23 00:12:03 UTC 949 0ERROR:  canceling statement due to  
statement timeout
2009-03-23 00:12:03 UTC 949 0STATEMENT:  SELECT count(*) from instance  
group by id order by id ;

node 1:
2009-03-23 00:12:03 UTC 9075 0ERROR:  syntax error at or near "send"  
at character 1
2009-03-23 00:12:03 UTC 9075 0STATEMENT:  send invalid query from  
pgpool to abort transaction

Thank you,
