Re: pg_upgrade from Postgresql-12 to Postgresql-13 fails with "Creating dump of database schemas postgres *failure*"

Hi Jeff,

Could you please clarify what core files are? I am truly a newbie to postgresql. 

The pg_dump on both `postgres` and `postgis_raster` databases ran without error.  Attached is the posgtresql log. 

Thank you,
Chow

Here are the logs: pg_upgrade_server.log, pg_upgrade_dump_13427.log and tail_postgresql-12-2022-02-16_190344.log.

From that last log file we have:

1. 2022-02-16 19:04:35 +08 [303982]: [4957-1] session=620cda42.4a36e,user=postgres,db=postgis_raster,app=pg_dump,client=[local] | LOG:  disconnection: session time: 0:00:01.101 user=postgres database=postgis_raster host=[local]
2. free(): invalid pointer

and then a little later:

1. 2022-02-16 19:04:35 +08 [303791]: [7-1] session=620cda0f.4a2af,user=,db=,app=,client= | LOG:  server process (PID 303982) was terminated by signal 6: Aborted

Do you get any core files for 303982?  Do you have core dumps enabled?  What do you get if you run a manual pg_dump -s on db postgis_raster?

Cheers,

Jeff
