On OSX the regular readline (really libedit) library likes to put strange stuff into history files --- it turns spaces, backslashes, and I don't know what else into backslash-octal escape sequences. It manages to reverse the transformation just fine on read though. What it looks like to me is that you've started linking psql with some other version of readline that doesn't follow that convention, and accordingly shows you strange things from the history file. When/if you go back to libedit, it likely won't like the history entries the other library made. Short answer: stick to one readline library. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers(a)postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
