Hi!
I'm running a query that is causing the server to segfault.
This is the plan generated by setting "enable_incremental_sort" to off.
setting the option to "on", causes:
# 2020-10-30 14:49:06 -03 - - 519945 - - () : LOG:background worker "parallel worker" (PID 522547) was terminated by signal 11: Segmentation fault
# 2020-10-30 14:49:06 -03 - ::1(46826) - 521801 - username- (database_name) : WARNING: terminating connection because of crash of another server process
# 2020-10-30 14:49:06 -03 - ::1(46826) - 521801 - username - (database_name) : DETAIL: The postmaster has commanded this server process to roll back the current transaction and exit, because another server process exited abnormally and possibly corrupted shared memory.
# 2020-10-30 14:49:06 -03 - ::1(46826) - 521801 - username - ( database_name) : HINT: In a moment you should be able to reconnect to the database and repeat your command.
Running explain only gives the following plan:
Version:
PostgreSQL 13.0 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 8.3.1 20191121 (Red Hat 8.3.1-5), 64-bit
