I expected that, because the name "GMT" is hard-wired in our code. Doesn't help for postgres_fdw though, because it has "UTC" hardwired.

Using current PG HEAD (with tzdata release 2024a): =# select count(*) from pg_timezone_names; count ------- 597 (1 row) I can believe older tzdata releases varying from that a little, but they haven't exactly been adding zone names at a rapid clip. Either the one you're dealing with is VERY old or it lost some files sometime. regards, tom lane
