Several of the developers have tried to reproduce this bug, with no
success.

Exactly how do you set the time zone?  What does "SHOW TIMEZONE" show?
What do you get from
    select timestamp('1993-04-01');
    select timestamp('1993-04-02');
    select timestamp('1993-04-03');

One reason I'm so interested in your timezone is that 1993-04-02 is not
a DST transition day in any timezone that I know about.  In Europe, DST
transitions happen in the last week of March, never in April, according
to the references I can find.  In the USA, we do have transitions in
April, but the transition day in 1993 was 04-04.
