Description:

Hi,

I am playing around chdb (https://github.com/chdb-io/chdb), which is an
embedded clickhouse engine. The python binding of chdb enables the usage
with plpython3.

The following anonymous block causes a server termination:
======= 
do language plpython3u $$
import chdb
chdb.query(sql='''select * from
s3('https://datasets-documentation.s3.eu-west-3.amazonaws.com/aapl_stock.csv')
limit 10''')
$$
=======

The related logs:
=======
2023-12-04 13:36:28.086 UTC [3202531] LOG:  server process (PID 3216826) was
terminated by signal 6: Aborted
2023-12-04 13:36:28.086 UTC [3202531] DETAIL:  Failed process was running:

        chdb.query(sql='''select * from
s3('https://datasets-documentation.s3.eu-west-3.amazonaws.com/aapl_stock.csv')
limit 10''')
        $$

2023-12-04 13:36:28.087 UTC [3202531] LOG:  all server processes terminated;
reinitializing
=======

I've experimented just fine with several other features, e.g., queries &
file table function.

I am not sure if here is the right place to raise the issue. I've reported
on the github repo (https://github.com/chdb-io/chdb/issues/139) but it seems
not a chdb issue because the query runs fine within a chdb python session.

Thanks.

The useful details would have appeared *before* this message.
Look for TRAP: lines, or possibly python-generated messages.
(This could easily have been a python-internal abort, rather
than anything Postgres did.)  Also there might be a stack trace.
