[pgpool-general: 8886] pgpool 4.4.2 error after upgrade

[Maria Nieva]

Hi,

I recently upgraded pgpool from 4.1.1 to 4.4.2.  I saw in the pgpool logs
this error.

2023-07-08 00:39:20.825 [unknown] PROCESS: CHILD DB: pie2 USER:  APPL:
[unknown] ERROR:  invalid memory alloc request size 18446744073709551592
2023-07-08 00:39:20.825 [unknown] PROCESS: CHILD DB: pie2 USER:  APPL:
[unknown] CONTEXT:  while searching system catalog, When relcache is missed

When I google the error, it seems related to postgres.  However, when I
look into the postgres logs, I do not see the error.  Also the logs in
4.1.1 do not have the same error.  I am unsure why I'm getting the error in
4.4.2.

The postgres is in version 14.5.  The db size is 1.4TB.  The OS is Ubuntu
20.  We installed pgpool from source.

wget https://www.pgpool.net/mediawiki/images/pgpool-II-4.4.2.tar.gz
tar -xvzf pgpool-II-4.4.2.tar.gz
cd pgpool-II-4.4.2/
./configure --prefix=/local/opt/points/pgpool4.4.2 --enable-sequence-lock
make ; make install

I have attached the pgpool logs for both versions.

I hope to get clarity on what caused the error and how to resolve this.
