First:
When committing, I has a problem with conflicts. It seems that while
resolving these conflicts, a line got lost. I re-added that line.

Second, this problem is known, but there is no good solution to this problem,
except not leaving connected to true. (which is bad practice anyway IMHO).

There are more problems: the library name is not cross-platform, so the
project will no longer be cross-platform. Which is a far more serious
problem, IMHO. (and one which would exist even if I had followed your
suggestion of implementing the property in TSQLConnection).
