I'd recommend doing it in C ... the flexibility is there, and the
performance will be better too. There are several examples of C-coded
triggers in contrib:

contrib/fulltextindex/fti.c
contrib/lo/lo.c
contrib/noupdate/noup.c
contrib/spi/autoinc.c
contrib/spi/insert_username.c
contrib/spi/moddatetime.c
contrib/spi/refint.c
contrib/spi/timetravel.c
contrib/tsearch/txtidx.c

Some of these are probably very close to what you want already.
