Bug reference: 4547
Logged by: Ferdinand Gassauer
Email address: gassauer(at)kde(dot)org
PostgreSQL version: 8.3.5
Operating system: any
Description: sort columns in \d
Details:

currently the columns are sorted by attnum (not very userfriendly) instead
of attname (userfriendly)

this patch fixes this and makes the output of \d much more usable.

thank you for listening
