I'm not exactly sure what that error message is saying, though it is 
showing two different version of Postgres in use. Since pg_dump will not 
dump from a Postgres version newer then it's version, I'm going to say 
that you used the Postgres 16 version of pg_dump against the Postgres 14 
instance. Then used the Postgres 14 version of pg_restore to restore 
that dump file to the 14 instance. As Tom Lane mentioned that will not 
work as the older version(14) of pg_restore will not recognize the newer 
file version from the dump file(16). I don't have an answer for how you 
sort that out in the Zulip process.
