That's the best theory I can come up with either, although libpq's APIs haven't really changed in any non-backwards-compatible fashion in years. I could imagine a newer psql flat-out crashing because it tries to call some libpq function that doesn't exist in an older libpq, but that's not what we're seeing here. It's really weird. A couple of tests that might help narrow things down: 1. In the server configuration, enable log_connections, log_disconnections, and log_statement = 'all'. Does anything show up in the log when you connect with the broken psql and issue commands? 2. If you issue commands that span multiple lines --- unclosed left parens, multiline string literals, missing semicolons --- does the psql prompt change to match? regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
