Comment(by mmetz):
Replying to [comment:2 pertusus]:
> I use a centos 6, by no mean an old platform, but sqlite here is
sqlite-3.6.20, thus I think that relying, in the default case on that
feature is not a good idea. Updating system sqlite is a very bad idea,
using a non system sqlite for grass is very impractical (and prevents
updating packages).

> Also, I read the standard
http://www.contrib.andrew.cmu.edu/~shadow/sql/sql1992.txt, and it seems to
me that the "63)Subclause 13.8" says that for "Entry SQL" there should
only be one value, which explains why this feature is that badly
implemented in SQL implementations. According to the sqlite news, sqlite
3.7.11 dates from 2012-March-20!
I have fixed r53891 in r55271. No more batch insert, but the module is now
about 50x faster than the batch insert, using old-fashioned begin/commit
transaction.
