Hi hackers,
Here's a patch to add psql tab completion for the recently-added ALTER
TYPE … RENAME VALUE feature (thanks to Tom for fixing it up and
committing it).
It's modelled on the ALTER TYPE … RENAME ATTRIBUTE completion, but
tweaked to return string literals instead of identifiers.

- Twitter seems more influential [than blogs] in the 'gets reported in
the mainstream press' sense at least. - Matt McLeod
- That'd be because the content of a tweet is easier to condense down
to a mainstream media article. - Calle Dybedahl
