[$] The PostgreSQL community debates ALTER SYSTEM

Sometimes the smallest patches create the biggest discussions. A case in
point would be the process by which the PostgreSQL community — not a group
normally prone to extended, strongly worded megathreads — resolved the question of
whether to merge a brief patch adding a new configuration parameter.
Sometimes, a proposal that looks like a security patch is not, in
fact, intended to be a security patch, but getting that point across can be
difficult.
