Has anyone run into This?
Psycopg3 fails to resolve timezone localtime on MacOS (Catalina).
It falls back to UTC regardless of whether running with/without the
tzdata package which I did try.
There is a /etc/localtime symlink on this box pointed at the correct
file in the tz data directory, which apparently doesn't get used.
Adding a temporary symlink directly into the tz data directory got
things working but I'm skeptical of such a hack.
Also tested w/PSYCOPG_IMPL=python. Same results.
Psycopg2 had no issues.
Please advise.
Thx
