auto_explain causes cluster crash if pg_ctl reload is used (not pg_ctl restart) - Mailing list pgsql-bugs

Tried on both
PostgreSQL 9.0.4 on x86_64-unknown-linux-gnu, compiled by GCC gcc
(GCC) 4.1.2 20080704 (Red Hat 4.1.2-48), 64-bit
and
PostgreSQL 9.0.3 on x86_64-unknown-linux-gnu, compiled by GCC gcc
(GCC) 4.1.2 20080704 (Red Hat 4.1.2-48), 64-bit

shared_preload_libraries = 'pg_stat_statements,auto_explain'
custom_variable_classes = 'auto_explain'
auto_explain.log_min_duration = '10s'
auto_explain.log_analyze = true
auto_explain.log_buffers = true

I was testing to see if any of the settings above got applied after
issuing a "pg_ctl reload" rather than a restart, and I was surprised
to see that I could crash my db cluster. I realize that the docs say
to issue a restart, but the crash seems a tad user-unfriendly.

Any other details I should provide?
