b67aaf21e8 Add CASCADE support for CREATE EXTENSION.
Without CASCADE, if an extension has an unfullfilled dependency on
another extension, CREATE EXTENSION ERRORs out with "required extension
... is not installed". That is annoying, especially when that dependency
is an implementation detail of the extension, rather than something the
extension's user can make sense of.

In addition to CASCADE this also includes a small set of regression
tests around CREATE EXTENSION.

0426f349ef Rearrange the handling of error context reports.
Remove the code in plpgsql that suppressed the innermost line of CONTEXT
for messages emitted by RAISE commands.  That was never more than a quick
backwards-compatibility hack, and it's pretty silly in cases where the
RAISE is nested in several levels of function.  What's more, it violated
our design theory that verbosity of error reports should be controlled
on the client side not the server side.

To alleviate the resulting noise increase, introduce a feature in libpq
and psql whereby the CONTEXT field of messages can be suppressed, either
always or only for non-error messages.  Printing CONTEXT for errors only
is now their default behavior.

The actual code changes here are pretty small, but the effects on the
regression test outputs are widespread.  I had to edit some of the
alternative expected outputs by hand; hopefully the buildfarm will soon
find anything I fat-fingered.

In passing, fix up (again) the output line counts in psql's various
help displays.  Add some commentary about how to verify them.

cac7658205 Add transforms feature
This provides a mechanism for specifying conversions between SQL data
types and procedural languages.  As examples, there are transforms
for hstore and ltree for PL/Perl and PL/Python.
