Yes, I've encountered a similar issue, this time with ALTER (TEXT SEARCH
CONFIGURATION):
CREATE TEXT SEARCH CONFIGURATION ispell_tst (COPY=english);
CREATE TEXT SEARCH DICTIONARY ispell (Template=ispell, DictFile=ispell_sample, AffFile=ispell_sample);
ALTER TEXT SEARCH CONFIGURATION ispell_tst ALTER MAPPING FOR word, word WITH ispell;
ERROR:  tuple already updated by self

And again, I could not get similar errors with all the other ALTER commands,
that accept lists.

Sorry for mixing two different problems together, I should have reported it
separately.
