FTI contrib

(Cross-posted to -hackers)

Hi,

The latest patch we submitted to the fulltextindex module improved lots of
things but something we could not get to work was the apparently correct use
of the PG_GETARG* macros, etc.

Whenever we used these macros, we always got 0 or NULL as our values. So,
we reverted to the trigger->tgargs array. Looking at the macro, it's
accessing fcinfo->arg[n] array. For us, the fcinfo->arg array was always
empty.

What's going on? Although it works, someone with more experience might want
to have a quick look at it. The problem is that we suspect it will fail if
someone tries to FTI a TOAST-ed column.
