[Dbix-class] SQL::Translator 0.08 - needed for release

[Jess Robinson]

I keep getting thumped about this, so here goes:

In general, 0.08_01 seems usable, since many DBIx::Class folks are already 
using it, so if I've missed any complaints or patches, please send them to 
me or the sqlfairy list.

What I'd like to add/finish, before releasing 0.08 is a chunk of fixing to 
the diffing code, currently it lives in its own little world, and makes up 
the SQL as it goes along (See SQL::Translator::Diff, extracted from 
sqlt-diff into a module). I've been adding functions to the 
database-Producer modules like "alter_field", "add_field", "drop_field" 
which produce the sql needed for the appropriate database, given SQLT 
schema objects (c.f. SQL::Translator::Schema::Field etc). These are still 
needed in some places, e.g. SQLite, which only supports a minimal subset 
of ALTER, and probably needs DROP TABLE, CREATE TABLE for most things 
(ick).

So SQL::Translator::Diff needs to:

1) check if the producer its asked to translate to supports diffing (i.e.
    the alter functions)
2) actually call the alter functions to produce the SQL
3) probably be split into "diff_table", "diff_field" etc to make
    it more readable.
4) still pass it's tests ;)
5) have tests for all the different DBs supported
6) ?? - I must have missed something..

Then I think we're good to go.. Any volunteers? tests? ;)
