Oops! I made a mistake, which clearly showed up in my last email: I forgot
to psql back in as "tester".
Now I get the right behavior:
$ psql postgres tester
psql (9.4.5, server 11devel)
Type "help" for help.
postgres=> select pg_read_file('/Users/postgres/temp');
ERROR: absolute path not allowed
Thanks for bearing with me. So far so good on this feature, going to run
the tests too.
Best,
Ryan
