The underlying macOS platform looks a bit hoary as well. (You gain exactly zero points for good maintenance practice on the local side either, since PG 13's current release is 13.14. If you're going to install Postgres and then ignore bug-fix releases for multiple years, I counsel not starting from a dot-zero release. However, that doesn't seem to be related to your immediate problem.) Having said that, > * The EXACT TEXT of the error message you're getting, if there is one: > ERROR: invalid value for parameter "TimeZone": "UTC" > CONTEXT: remote SQL command: SET timezone = 'UTC' That's just bizarre. There is no release of Postgres anywhere, at any time in the past couple decades, that should not think that "UTC" is a valid timezone setting. My best guess is that the remote was built with a --with-system-tzdata setting that's not actually valid for its platform. Short answer: your remote database is very incompetently administrated. If the remote's DBA is not willing to work on fixing it, I suggest finding a job where you don't have to deal with that. regards, tom lane
