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.
(I have a todo item to rationalize that...)

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.
