Re: Directory/File Access Permissions for COPY and Generic File Access Functions

I think the way this should work is that if you create a DIRALIAS, then
the COPY command should refer to it by logical name, e.g.,

CREATE DIRALIAS dumpster AS '/tmp/trash';
COPY mytable TO dumpster;


If you squint a bit, this is the same as a tablespace.  Maybe those two
concepts could be combined.

On the other hand, we already have file_fdw, which does something very
similar.
