I reviewed this for some time today.
The patch applies with hunks, compiles and tests are passed, though it
looks like not having additional test along with it.
- in hstore_plpython.c, PLyParsers parsers = { .in = hstore_to_dict, .out = dict_to_hstore }; I'm not sure if
thiscoding style is used anywhere in the core.
Isn't this the C99 style?
- You need define custom variable class to use this feature.
plpython.hstore = 'public.hstore'. I wonder why it's called
plpython[u].hstore = 'public.hstore' (with 'u') because the language
is called "plpythonu".
- typo in plpython.h, Types for parsres functions that ...
- I tried the sample you mention upthread, regression=# select pick_one('a=>3, b=>4', 'b'); ERROR: TypeError: string

My python is 2.4.3 again.
That's it for now. It is an exciting feature and plpython will be the
first language to think of when you're building "object database" if
this feature is in. The design here will affect following pl/perl and
other so it is important enough to discuss.
