Yes, I was wondering about that a bit, feeding a single typcache entry
across the board. And while looking at the code, I was reminded about
the following exceptions:
extended_stats_funcs.c: if (typid == TSVECTOROID)
stat_utils.c: if (*atttypid == TSVECTOROID)
stat_utils.c: if (atttypid == TSVECTOROID)
I think that the existing code is also broken when defining a domain
over tsvector if we don't feed a domain base type in these three
spots.
