Some time ago (may 2001) there was some talk in firebird-devel list about
enhancements of events. It looks as if Dmitry Yemanov already had
implemented the change. But don't know if this change has made it into the
current release - the whatsnew.txt doesn't mention it but I saw some notes
in the changelog.
Below is a part of Dmitry's message - I'll send you the full message in
private since its a bit long.

bye,
Markus

Hi,

I have practically finished (at least I think so) the work with the events
enhancement (* and ? wildcards support was added). Unfortunately, I had only
about 2-3 hours per week to work on it, so this plan was achieved later than
I expected. I could commit the source files (as well as win32 binaries)
right now, but I would prefer to get some feedback before making this step.
You can find the brief explanation of the changes I made and questions I
need to have answered below.

IMPLEMENTATION

Files touched: event_proto.h, event.h, event.c, utl.c, dfw.e, why.c (all in
/jrd)
