I have to hit the return key by hand to see the effect. Moreover, the pasted line has a highlighted background. > Second observation > When I copy _several_ lines of SQL commands from the Text Edit app and then paste them into psql, none of the newlines are respected. (I still get the strange highlight.) Now when I hit the return key, I get errors like this: > \i: extra argument "<the text of the line>" ignored FWIW, I'm not seeing that here, with Big Sur 11.2 and up-to-date Postgres. In a typical Postgres build, most of psql's input behavior is not determined by psql itself, but by libreadline (or possibly libedit, if PG was configured to use that instead). I speculate that your build switched to a newer version of readline or libedit, and it's behaving differently than you're used to. You could get some info about this by applying "otool -L" to the psql executable. On my laptop I see $ otool -L /Users/tgl/testversion/bin/psql /Users/tgl/testversion/bin/psql: /Users/tgl/testversion/lib/libpq.5.dylib (compatibility version 5.0.0, current version 5.14.0) /usr/lib/libedit.3.dylib (compatibility version 2.0.0, current version 3.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1292.60.1) of which the relevant bit for this purpose is "/usr/lib/libedit.3.dylib", pointing to the Apple-supplied version of libedit. Maybe you see something else? regards, tom lane
