The following bug has been logged on the website:
Bug reference: 18944
Logged by: Nikita Kalinin
Email address: n.kalinin@postgrespro.ru
PostgreSQL version: 18beta1
Operating system: ubuntu 22.04
Description:
Hello! When I execute the following query:
psql <<EOF
CREATE TABLE psql_pipeline(a INTEGER PRIMARY KEY, s TEXT);
\startpipeline
COPY psql_pipeline FROM STDIN;
\syncpipeline
\endpipeline
EOF
with `idle_session_timeout` set to, for example, 10000, I get the following
error:
FATAL: terminating connection due to idle-session timeout
psql: common.c:1501: discardAbortedPipelineResults: Assertion
`pset.available_results > 0' failed.
[1] 1747708 abort (core dumped) psql <<<''
