Subject: BUG #18119: Failed assert while recoverying from pg_basebackup
Date: Wed, 20 Sep 2023 13:12:52 +0000
Message-ID: <18119-5f60199d6207f4d1@postgresql.org> (raw)
The following bug has been logged on the website:
Bug reference: 18119
Logged by: Bowen Shi
Email address: zxwsbg@qq.com
PostgreSQL version: 16.0
Operating system: centos
Description:
Dears,
There may be some problems in recovery. The following step can stably
reproducing the problem:
Firstly, run following script in master. To make sure that we have at
least
20GB data.
1. create table t(a int);
2. echo "insert into t select generate_series(1,5000);">script.sql
3. pgbench --no-vacuum --client=25 -U postgres --transactions=10000 --file
script.sql
Secondly, using pg_basebackup with stream mode
1. pg_basebackup --checkpoint=fast -h localhost -U postgres -p 5432 -Xs
-Ft
-v -P -D /data2/sqpg/inst/data_b
2. pgbench --no-vacuum --client=25 -U postgres --transactions=3000 --file
script.sql (Run this script concurrently during pg_basebackup)
Thirdly, we start the backup instance
cd /data2/sqpg/inst/data_b
tar xvf base.tar
mv pg_wal.tar pg_wal/
cd pg_wal
tar xvf pg_wal.tar
cd ../
echo "port=5433">>postgresql.conf
echo "log_min_messages=debug1">>postgresql.conf
echo "checkpoint_timeout=30s">>postgresql.conf
cd /data2/sqpg/inst/bin
./pg_ctl start -D ../data_b -l logfile_b
This problem was first found in PG 15, see following link for details:
https://www.postgresql.org/message-id/flat/20230227.120101.1600358770821352577.horikyota.ntt%40gmail...
And it still exists in PG 16.
