Doesn't prove a thing. The libc state I'm thinking of would be
recomputed on first use within a given process, ie, per backend.
So we still have no idea if the problem is libc's or Postgres'.

Given that the problem seems to be specific to your timezone,
and Postgres itself knows very little about timezones, a libc bug
is well within the realm of possibility.

Is anyone else able to reproduce this misbehavior at a DST boundary?
