Thanks Tom Lane. It's useful to know that one of these handles unentered text. postgres93.app is supplied with its own version of libedit. user@hostname:~ $ otool -L `which psql` /Applications/Postgres93.app/Contents/MacOS/bin/psql: /Applications/Postgres93.app/Contents/MacOS/lib/libpq.5.dylib (compatibility version 5.0.0, current version 5.6.0) /Applications/Postgres93.app/Contents/MacOS/lib/libssl.1.0.0.dylib (compatibility version 1.0.0, current version 1.0.0) /Applications/Postgres93.app/Contents/MacOS/lib/libedit.0.dylib (compatibility version 1.0.0, current version 1.45.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0) Do you think this an indication that the app bundle may have been compiled with a bad version of libedit? I can file a bug report along those lines.
