Re: Add default role 'pg_access_server_files'

The following review has been posted through the commitfest application:
make installcheck-world:  tested, passed
Implements feature:       tested, passed
Spec compliant:           not tested
Documentation:            tested, passed

I ran make installcheck-world and all tests passed except one that is a known issue with the way I have my environment
setup(ecpg tests unrelated to this patch).
 

Manual tests I ran to see if it Implements the Feature:

1) confirmed that superuser can call pg_read_file() to read files in or out of data directory
2) confirmed that "tester" can call pg_read_file() only if given EXECUTE privilege
3) confirmed that "tester" can only call pg_read_file() on a file OUTSIDE of the data directory iff I "grant
pg_access_server_filesto tester;"
 

Documentation seems reasonable.

I believe this patch to be Ready for Committer.

The new status of this patch is: Ready for Committer
