We're considering switching to InnoDB tables for a couple of tables in
our database where we need transactions. We're complete newbies with
reference to innodb, although we are seasoned veterans with regards to
MySQL/MyISAM and general concepts.

I've actually noticed this in the past several releases; I apologize for
not mentioning it sooner.

and part-way through, it fails.

This may be by design, but I figured I'd bring it up because it caused
less-than-desirable behaviour for me. I executed an alter table query, designed to
change the length of a fixed width char field to 128 from 255. The alter occured fine,
with no problems, except that there were

mysql CREATE TABLE tablename (value1 int(10) AUTO_INCREMENT, value2 timestamp(14),

Sounds like you should either:
ALTER TABLE telegramme ADD INDEX combined (to_id, owner_id);
or
SELECT * FROM telegramme WHERE to_id = 3157 UNION SELECT * FROM telegramme WHERE
owner_id = 3157;
