1996 is when the open-source Postgres effort started.

There's a bigger philosophical issue here, which is whether a new file
shouldn't just list the current year as the initial copyright year.
In this case, a lot of the code in execScan.h was formerly in
execScan.c, so copying its copyright notice seems like clearly the
right thing.  We've generally taken the attitude that most stuff in
Postgres has pretty clear traceability to older work, so we prefer
to use the same copyright dates as related older files even in less
clear-cut cases.
