If you want to promote postgreSQL, then it should be good that anything
from outside (whether standard or not) can work with postgreSQL, but
anything that work in pg may not work outside;-)
This pseudo portability strategy is used by Oracle, IBM, M$ or mysql...
That makes you're clients stay with you longer;-) So usually it is a
success...
semi joke: I was not aware that there is such a thing as an SQL standard.
I have the O'Reilly book about SQL, which declines *every* command for
SQL Server, Oracle, MySQL, PostgreSQL...

Sure, it is possible to do it so. But if it is in the default
installation, it would help me;-)
From my point of view, my students come from a java first course, so they
have to learn again some new syntax and new operators. Small stuff, but
it can help to say "same as java" and go on to new concepts.
Also, if I add some new operators in pg_operator, say && for AND, I'm not
sure the optimiser will know that is a AND and take that into account.

Yep.
