For the logic that replaces outdated codes, see hist-oldCode.

In the Postgresql version, the test above was:

    if c.rel == abbrMod.REL_SIMPLE:

However, since abbrMod.REL_SIMPLE is one space, the MySQL version of the database returns an empty string, hence the more general test above which works correctly with either an empty string or a single space.
