Existing client connections should not be able to notice a reload that
changes pg_hba.conf or pg_ident.conf; however they definitely *should*
notice a reload that changes postgresql.conf (at least for parameters
that aren't overridden by other cases, such as a SET in the current
session). So the blanket statement Marc is making is simply wrong.
Whether there is a bug here is impossible to say given the limited
amount of information provided. I'd not expect a reload to cause
an existing connection to become totally dysfunctional, which is
what Marc seems to be claiming ... but without more evidence or
a test case, there's not much to be done.
