@Ericson,
Forgive me for seeming dense, but how does COPY help or hurt here?
@Andreas,
I had to laugh at your reference to "prose". Would you believe I am
actually a published playwright? Long before I started coding, of
course. Old habits die hard.....
The script code via Python/Django/psycopg2 would be helpful as my
suspicion is that you are seeing the effects of open transactions.
entry_search_vector_trigger
BEGIN
SELECT setweight(to_tsvector(NEW.title), 'A') ||
setweight(to_tsvector(NEW.content), 'B') ||
setweight(to_tsvector(NEW.category), 'D') ||
setweight(to_tsvector(COALESCE(string_agg(tag.tag,
', '), '')), 'C')
INTO NEW.search_vector
FROM ktab_entry AS entry
LEFT JOIN ktab_entry_tags AS entry_tags ON
entry_tags.entry_id = entry.id <http://entry.id>
LEFT JOIN ktab_tag AS tag ON tag.id <http://tag.id> =
entry_tags.tag_id
WHERE entry.id <http://entry.id> = NEW.id
GROUP BY entry.id <http://entry.id>, category;
RETURN NEW;
END;
tag_search_vector_trigger
BEGIN
UPDATE ktab_entry SET id = id WHERE id IN (
SELECT entry_id FROM ktab_entry_tags WHERE tag_id = NEW.id

RETURN NEW;

I think COPY bypasses the triggers.

I am not (yet) posting the trigger code because this post is
long already, and if your answers are 1) yes, 2) no and 3)
triggers often work / fail like this, then there’s no point
and we can wrap this up. But if not, I will happily post
what I have. Thank you.
This is too much prose for the regular programmer, show us the
code, and point out what doesn't work for you, then we can help:-)
