<>I have problem with a new server that crashes when restoring data to it. It's around 1.5 TB of raw data with both spatial and raster data.

I have done some more testing and postgres also crashes right after 'pg_restore --section=pre-data -1' is done also. Here I also see the 'free(): invalid pointer' in the postgres log.
This happens on with Postgres 12 and Postgres 13. and any version of postgis I have tested with.
The pre-data input is little bit more than 200.000 lines with more than 6000 CREATE statements, if I test with the first 100 lines it does not crash. It seems like no data are lost here because the server does recovery at startup.
I tested on another with CentOS and the same software and it worked ok
The server diagnostic does not indicate any memory errors.
