David, It appears that the problem is related to the fact that MacOSX does not really use the libreadline (checks and you will see that it is a symlink to libedit.) I asked this question a year or so ago and Tom Lane said that when the history file was closed that the libedit did not return the right status code. I got rid of the error message by changing the source to ignore the return code... Currently I simply ignore the error message :) and use tools that have reduced my usage of psql to a bare minimum.
