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?
