Subject: Running the fdw test from the terminal crashes into the core-dump
Date: Sun, 18 Feb 2024 21:33:07 +0300
Message-ID: <4d65a385-7efa-4436-a825-0869f89d9d92@postgrespro.ru> (raw)
Hi, hackers!
After starting the server (initdb + pg_ctl start) I ran a regress test
create_misc.sql ('\i src/test/regress/sql/create_misc.sql') and, after
that,
I ran the fdw test ('\i contrib/postgres_fdw/sql/postgres_fdw.sql') in
the psql, and it failed in the core-dump due to the worked assert.
To be honest, such a failure occurred only if the fdw extension was not
installed earlier.
script to reproduce the error:
./configure CFLAGS='-g -ggdb -O0' --enable-debug --enable-cassert
--prefix=`pwd`/tmp_install && make -j8 -s install
export CDIR=$(pwd)
export PGDATA=$CDIR/postgres_data
rm -r $PGDATA
mkdir $PGDATA
${CDIR}/tmp_install/bin/initdb -D $PGDATA >> log.txt
${CDIR}/tmp_install/bin/pg_ctl -D $PGDATA -l logfile start
${CDIR}/tmp_install/bin/psql -d postgres -f
src/test/regress/sql/create_misc.sql &&
${CDIR}/tmp_install/bin/psql -d postgres -f
contrib/postgres_fdw/sql/postgres_fdw.sql
The query, where the problem is:
-- MERGE ought to fail cleanly
merge into itrtest using (select 1, 'foo') as source on (true)
when matched then do nothing;

This error is consistently reproduced.
To be honest, I wasn't able to fully figure out the reason for this, but
it seems that this operation on partitions should not be available at all?
alena@postgres=# SELECT relname, relkind FROM pg_class where
relname='itrtest';
relname | relkind
